Abstract: | ABSTRACT: The aim of this thesis is to compute the Euler Characteristic of the Bestvina-Brady groups. First, the analytical topology, the point-set topology is introduced. Then, the
main purpose of the use of algebraic topology; the homeomorphism problem is stated.
To understand the homeomorphism problem, certain well-known topological spaces
are defined, and to solve it, the notion of topological invariants is introduced. Two
main topological invariants; Euler characteristic and the Fundamental group theories
are studied. Finally, by the use of C.T.C. Wall and the Bestvina-Brady papers, under
certain homotopic conditions the Euler Characteristic of the Bestvina-Brady groups is
computed. Keywords: Topological invariants, Euler Characteristic, Fundamental Group, Bestvina - Brady Group.

ÖZ: Bu tezin amacı Bestvina-Brady grupların Euler karakteristiğini hesaplamaktır. İlk
olarak analitik topoloji çeşidi olan nokta-küme topolojisi tanımlanmıştır. Sonrasında,
cebirsel topolojinin başlıca amacı olan homeomorfizm problemi tanımlanmıştır. Homeomorfizm problemini anlayabilmek için, iyi bilinen bazı topolojik uzaylar tanımlanmı
ştır. Topolojik değişmezlerin tanımı verilmiş ve homeomorfizm problemini çözmede
nasıl kullanıldıkları anlatılmışstır. İki temel topolojik değişmez konusu çalışılmıştır;
bunlar Euler karaktersitik ve Fundamental grup teorileridir. Son olarak, C.T.C. Wall
ve Bestvina-Brady çalışmaları referans baz alınarak Bestvina-Brady grupların Euler
karakteristiği hesaplanmıştır. Anahtar kelimeler: Topolojik değişmezler, Euler karakteristik, Fundamental grup, Bestvina-Brady grup. |
