The Atılım University Department of Mathematics was founded in 2000 and it offers education in English. The Department offers students the opportunity to obtain a certificate in Mathematical Finance or Cryptography, aside from their undergraduate diploma. Our students may obtain a diploma secondary to their diploma in Mathematics with the Double-Major Program; as well as a certificate in their minor alongside their diploma in Mathematics through the Minor Program. Our graduates may pursue a career in academics at universities, as well as be hired in sectors such as finance, education, banking, and informatics. Our Department has been accredited by the evaluation and accreditation organization FEDEK for a duration of 5 years (until September 30th, 2025), the maximum FEDEK accreditation period achievable. Our Department is globally and nationally among the leading Mathematics departments with a program that suits international standards and a qualified academic staff; even more so for the last five years with our rankings in the field rankings of URAP, THE, USNEWS and WEBOFMETRIC.

Abstract

Bu tezde, kompakt, bağlantılı, yönlendirilebilen cins sayısı $g \geq 1$ olan bir yüzey için E. Irmak ve M. Korkmaz'ın Hatcher-Thurston kompleksinin otomorfizma grubu üzerindeki çalışmalarını inceleyeceğiz. Daha açık olarak, bu otomorfizma grubunun yönlendirilebilen yüzeyin genişletilmiş gönderim sınıf grubunun merkezine bölümüne izomorfik olduğu gerçeği üzerinde çalışılmaktadır. Bu tezin son bölümünde, cins sayısı $g \geq 1$ olan kompakt, bağlantılı, yönlendirilemeyen yüzeyler için Hatcher-Thurston kompleksini ve kesme sistemlerini tanımlayacağız.
In this thesis, we study the work of E. Irmak and M. Korkmaz on the automorphism group of the Hatcher-Thurston complex for a compact, connected, orientable surface of genus $g \geq 1$. More precisely, it is shown that this automorphism group is isomorphic to the extended mapping class group of the orientable surface modulo its center. In the last chapter of this thesis, we define cut systems and the Hatcher-Thurston complex for compact, connected, nonorientable surfaces of genus $g \geq 1$.
