[2012. 6. 13] ILAS 1896 IMA Conference on Numerical Linear Algebra and Optimisation 

3rd IMA Conference on Numerical Linear Algebra and Optimisation 

10 – 12 September 2012 University of Birmingham 

The IMA and the University of Birmingham are pleased to announce the 3rd IMA Conference on Numerical Linear Algebra and Optimisation. 

Scope: 

The success of modern codes for large-scale optimisation is heavily dependent on the use of effective tools of numerical linear algebra. On the other hand, many problems in numerical linear algebra lead to linear, nonlinear or semidefinite optimisation problems. The purpose of the conference is to bring together researchers from both communities and to find and communicate points and topics of common interest. 

Conference topics include any subject that could be of interest to both communities, such as: 

· Direct and iterative methods for large sparse linear systems. 
· Eigenvalue computation and optimisation. 
· Large-scale nonlinear and semidefinite programming. 
· Effect of round-off errors, stopping criteria, embedded iterative procedures. 
· Optimisation issues for matrix polynomials. 
· Fast matrix computations. 
· Compressed/sparse sensing. 
· PDE-constrained optimisation. 
· Applications and real time optimisation. 

Invited Speakers: 

Roland Freund (University of California, Davis) 
Philip Gill (University of California, San Diego) 
Serge Gratton (IRIT-CERFACS, Toulouse) 
Anne Greenbaum (University of Washington, Seattle) 
Michael Hintermueller (Humboldt University, Berlin)

DESCRIPTION 

The main aim of the conference is to bring together diverse collection of researchers in graph theory, computer science and complex networks, interested in the applications of graph spectra, to discuss current trends and future directions in this area. 

Note that it is not necessary to submit an original paper in order to attend the conference: we would also like to hear a talk on your recently published results that use graph spectra! 

Abstract for a talk may be submitted via the EasyChair website at 
https://www.easychair.org/conferences/?conf=ags2012. 

Speakers who do not have an EasyChair account should sign up for an account from the above link, and then return to it again to submit an abstract. 

Abstract submission deadline (extended): June 10, 2012 
Abstract acceptance notification (extended): June 30, 2012 

Consequently, there will be no standard book of proceedings for the conference (just a book of abstracts). Instead, authors may submit their original research papers to a special issue of Discrete Applied Mathematics devoted to the conference theme. The deadline for submission of full papers is November 15, 2012. Papers will be subject to a strict review process managed by the Guest Editors: Francesc Comellas, Robert Elsasser and Dragan Stevanovic.

[2012. 2. 15] ILAS 1874 IMA Conference on Numerical Linear Algebra and Optimisation

3rd IMA Conference on 
Numerical Linear Algebra and Optimisation 

10 – 12 September 2012 
University of Birmingham 

CALL FOR PAPERS 

The IMA and the University of Birmingham are pleased to announce the 3rd IMA 
Conference on Numerical Linear Algebra and Optimisation. 

Scope: 
The success of modern codes for large-scale optimisation is heavily dependent on the use of effective tools of numerical linear algebra. On the other hand, many problems in numerical linear algebra lead to linear, nonlinear or semidefinite optimisation problems. The purpose of the conference is to bring together researchers from both communities and to find and communicate points and topics of common interest. 

Conference topics include any subject that could be of interest to both communities, such as: 
· Direct and iterative methods for large sparse linear systems. 
· Eigenvalue computation and optimisation. 
· Large-scale nonlinear and semidefinite programming. 
· Effect of round-off errors, stopping criteria, embedded iterative procedures. 
· Optimisation issues for matrix polynomials. 
· Fast matrix computations. 
· Compressed/sparse sensing. 
· PDE-constrained optimisation. 
· Applications and real time optimisation. 

Invited Speakers: 
Roland Freund (University of California, Davis) 
Philip Gill (University of California, San Diego) 
Serge Gratton (CERFACS, Toulouse) 
Anne Greenbaum (University of Washington, Seattle) 
Michael Hintermueller (Humboldt University, Berlin) 
Sabine van Huffel (K.U. Leuven) 
Mike Powell (University of Cambridge) 
Andrea Walther (University of Paderborn) 

Instructions for Contributors: 
Mini-symposium proposals and contributed talks are invited on all aspects of numerical linear algebra and optimisation. Mini-symposium proposals in plain text/LaTeX should be submitted to conferences@ima.org.uk by 30 March 2012. Organisers will be advised of acceptance by 10 April 2012.

[2012. 2. 6] ILAS 1871  CRM Conference on Applications of Graph Spectra  in Computer Science 

Second Announcement 
===========================================================
CRM CONFERENCE ON APPLICATIONS OF GRAPH SPECTRA IN COMPUTER SCIENCE 

July 16-20, 2012, Barcelona 

http://www.crm.es/Activitats/Activitats/2011-2012/GraphSpectra/web-graphspectra/
=========================================================== 

DESCRIPTION 

The spectra of matrices associated with a network are widely used to characterize its properties and to extract structural information. 
Applications of spectral graph theory may be easily found in
 combinatorial optimization (e.g., Goemans-Williamson MAXCUT algorithm), computer science (e.g., spectral clustering, expander graphs, pattern recognition) or complex networks (e.g., web page ranking, synchronization, epidemic thresholds). 

The aim of this conference is to bring together the diverse collection of researchers from graph theory, computer science and complex networks, who are interested in the theory and applications of graph spectra to discuss current trends and future directions in this area. The conference is expected to provide cross-fertilization of ideas, create more awareness among disparate groups of researchers and foster an increase in collaborations between theory- and application-oriented studies. For young researchers in particular, this will be an excellent opportunity to see the full scope of the subject and many interesting directions they can explore. 

ORGANIZATION 
The conference is organized and sponsored by 

Centre de Recerca Mathematica (CRM), Barcelona 
http://www.crm.es/ 

and co-sponsored by 

Ministry of Science and Innovation (MICINN), Spain. 

The conference will take place at CRM in Campus de Bellaterra, Edifici C, 08193 Bellaterra (Barcelona).

[2012.1. 30] ILAS 1867  Hans Schneider Prize

The Hans Schneider Prize is for research, contributions, and achievements at the highest level of Linear Algebra. The ILAS Executive Board is pleased to announce that the 2012 Hans Schneider Prize in Linear Algebra has been awarded to Thomas J. Laffey, of University College Dublin, Ireland. The award is made in recognition of Laffey's lifetime profound contributions to many areas of Linear Algebra, including integral matrices, simultaneous similarity, linear preservers, and, in particular, his breakthrough results on the inverse eigenvalue problem for nonnegative matrices. 

The following are just a couple of examples of Laffey's achievements. He proves (in a joint paper with Reams, 1994) that every square matrix over the integers with trace zero is a commutator of two integral matrices, thus providing an analogue to the classical result over fields. The nonnegative inverse eigenvalue problem (NIEP) asks for a characterisation of those lists of n complex numbers (possibly with repetitions) that comprise the spectra (with multiplicities) of n-by-n entrywise nonnegative matrices. Laffey (in a joint paper with Smigoc, 2006) completely solves the NIEP if the lists are selfconjugate and consist of one positive real number and and n-1 complex numbers with nonpositive real parts. 
Further, in a recent paper, Laffey brings new insight to the NIEP by giving an ingenious, elementary and constructive proof of the Boyle - Handelman theorem in an important special case. 

Laffey is well known in the mathematical community outside of Linear Algebra. He is heavily involved with the Irish team for the International Mathematical Olympiad. Laffey has been a member of the National Committee for Mathematics and represented Ireland at the International Congress of Mathematicians. A member of the Royal Irish Academy since 1981, he served as its Vice President for the period 1990 - 1992. Laffey's encyclopedic knowledge and enthusiasm for mathematics of all kinds have made him an invaluable source of information and advice for his colleagues and students alike. 

The Hans Schneider Prize will be presented to Professor Laffey at the next ILAS meeting in Providence USA, 3-7 June, 2013, and Laffey will also be invited to give a lecture at that meeting. 
The ILAS Executive would like to express its sincere thanks to the members of the 2012 Hans Schneider Prize Committee: Shmuel Friedland, Leiba Rodman (chair), Peter Semrl, Bryan Shader, and Valeria Simoncini. An outstanding group of people were nominated for the Prize, and the Prize Committee performed its duties with appropriate thoroughness and careful consideration. The Prize Committee's efforts are most appreciated.

 

[2012. 1. 11] ILAS 1866  2011 ILAS Election voting closes January 22, 2012

[2012.1. 10] ILAS 1864 2012 Shanghai Conference on Algebraic Combinatorics

The Shanghai Conference on Algebraic Combinatorics will take place during August 17 -- 22, 2012 at Shanghai Jiao Tong University, Dongchuan Road 800, Shanghai, 200240, China. 

August 17 is the registration day and the scientific program begins from August 18. 

The topics of this conference are algebraic combinatorics in the widest sense and many related directions in pure and applied mathematics and sciences. 

The academic committee of the conference consists of the following: 

Richard Stanley (MIT) 
Zhe-Xian Wan (Chinese Acad. Sci.) 
Qing Xiang (U. Delaware) 


The organizing committee of the conference consists of the following: 

Eiichi Bannai - bannai@sjtu.edu.cn 
Hao Shen - haoshen@sjtu.edu.cn 
Yaokun Wu - ykwu@sjtu.edu.cn 
Xiao-Dong Zhang - xiaodong@sjtu.edu.cn 


All talks in this conference are by invitation and we plan to arrange the following three kinds of talks: (i) 50 minutes main talks. (ii) 30 minutes talks. 
(iii) 15 minutes short talks. 

The current confirmed 50 minutes main speakers are listed below: 

Anders Björner (Royal Institute of Technology) 
Aart Blokhuis (TU-Eindhoven) 
Peter J. Cameron (U. of London) 
Henry Cohn (Microsoft) 
Robert L. Griess, Jr. (U. of Michigan) 
Tatsuro Ito (Kanazawa) 
Alexander A. Ivanov (Imperial College) 
Gil Kalai (Hebrew Univ.) 
William M. Kantor (U. of Oregon) 
Jacobus Koolen (POSTECH) 
Abhinav Kumar (MIT) 
Richard Stanley (MIT) 
Paul Terwilliger (Wisconsin) 
Zhe-Xian Wan (Chinese Acad. Sci.) 
Jiping Zhang (Peking Univ.) 
Chuanming Zong (Peking Univ.) 


If we have many speakers, we may have to adjust some 30 minutes talks to be 25 minutes long. We will try to avoid parallel sessions as much as possible. But it might be inevitable to arrange parallel talks for 15 minutes short talks and maybe, some 30 minutes (or 25 minutes) talks. 

Those who have interest to attend our conference are invited to drop a message to any member of the academic committee and/or organizing committee to register to the conference in which they should indicate whether or not they want to give a talk. The list of invited speakers will basically be fixed in June 2012. Early registration will be very much welcome. 

The registration fee for the conference is 1000 RMB for each participant. This will cover conference material, lunches, suppers, and coffees and teas during breaks. This fee will be collected when the participants come to the registration desk to get their conference name badges and other conference material. 

Important dates: 

April 30: registration closed. 
May 31: hotel reservation. 
June 30: Abstract submission. 


The address of the homepage of the conference is: 
http://math.sjtu.edu.cn/Conference/SCAC/ 

More information about the hotel, traffic and confirmed speakers will be available in our conference website gradually. Please also contact with our organizing committee if you have any concern on the conference organization.
