RAMIFICATION STRUCTURES FOR QUOTIENTS OF MULTI-EGS GROUPS

Di Domenico, Elena ; Gül, Şükran and Thillaisundaram, Anitha LU (2023) In International Journal of Group Theory 12(4). p.237-252
Abstract

Groups associated to surfaces isogenous to a higher product of curves can be characterised by a purely group-theoretic condition, which is the existence of a so-called ramification structure. Gül and Uria-Albizuri showed that quotients of the periodic Grigorchuk-Gupta-Sidki groups, GGS-groups for short, admit ramification structures. We extend their result by showing that quotients of generalisations of the GGS-groups, namely multi-EGS groups, also admit ramification structures.
