Istanbul Ayrik Matematik Toplantilari Seminer Duyurusu

Degerli Matematikciler,

Istanbul Ayrik Matematik Toplantilarinin bu donemin son toplantisi herzaman
oldugu gibi Istanbul Matematiksel
Bilimler Merkezinin (IMBM) cok guzel binasinda olucak.
Son toplantimizda 27 Nisan Cuma gunu saat 11.00'de
Josef Leydold  (WU Wien, Vienna, Austria) "Sign Patterns of Graph Laplacian
Eigenvectors" baslikli bir konusma yapacaktir.

Konusma konusuyla ilgili detaylari asagida ve ekteki ilanda gorebilirsiniz.

Seminer oncesi, saat 10.45'den itibaren cay-kahve ve kurabiye servisi
olacaktir. Konusmaya herkes davetlidir.

Abstract
The Laplacian matrix holds a lot of structural information about a given
graph.
In this talk we give a short introduction in the properties of this matrix
and its
eigenvectors. In particular we investigate their sign patterns, in
particular in the
number of so called nodal domains which are maximal components where the
vector
does not change sign.
