Automorphisms of the Hatcher-Thurston complex

Elmas Irmak, Mustafa Korkmaz

Published 2004-09-02, updated 2004-11-10Version 2

Let S be a compact, connected, orientable surface of positive genus. Let HT(S) be the Hatcher-Thurston complex of S. We prove that Aut(HT(S)) is isomorphic to the extended mapping class group of S modulo its center.
