Özet

If G is a Grigorchuk-Gupta-Sidki group defined over a p-adic tree, where p is an odd prime, we study the existence of Beauville surfaces associated to the quotients of G by its level stabilizers st(G)((n)). We prove that if G is periodic then the quotients G/ st(G)(n) are Beauville groups for every n >= 2 if p >= and n 3 if p = 3. In this case, we further show that all but finitely many quotients of G are Beauville groups. On the other hand, if G is non-periodic, then none of the quotients G= st(G)(n) are Beauville groups.
