The conference will be held on March 23-27, 2009 at Będlewo near Poznań. Będlewo is the Mathematical Research and Conference Center of the Polish Academy of Sciences (for further info about this place please visit www.impan.gov.pl/EN/Bedlewo).

This workshop will be the third in a series. The previous two workshops were held in Będlewo in 2005 and 2007. The aim is to bring together researchers sharing an interest in a variety of aspects of matrix analysis and its applications in other parts of mathematics and offer them a possibility to discuss current developments in these subjects.

Matrix theory is used in practically all other parts of mathematics and all areas to which mathematics is applied, and, in return, other parts of mathematics can be very useful in proving things about matrices, sometimes things that are very difficult or impossible to prove using conventional matrix theoretic methods. For example there are many examples in which graph theory is useful in matrix theory, but also matrix theory is an indispensable tool in graph theory. Yet another connection is with the people who are interested in polynomials (possibly in several variables) that take on only positive values. This involves many matrix problems both ways. Many advances have been made recently, both theoretically and practically (connections with semidefinite programming), with a lot of discussion between matrix people and others.

Researchers and graduate students in the area of linear algebra, statistical models and computation are particularly encouraged to attend the workshop. The format of this meeting will involve plenary talks and sessions with contributed talks. The list of invited will be opened by four winners of Young Scientists Awards of MAT-TRIAD 2007 (YSA 2007) promoted by the conference. We are also planning two short courses delivered by experienced lecturers for graduate students as well as others conference participants.

The work of young scientists has still a special position in the MAT-TRIAD'09. The best poster as well as the best talk of graduate students or scientists with a recently completed Ph.D. will be awarded. Prize-winning works will be widely publicized and promoted by the conference.
