Tits-type alternative for certain groups acting on algebraic surfaces

چکیده
A theorem of Cantat and Urech says that an analog the classical Tits alternative holds for group birational automorphisms a compact complex Kaehler surface. We established in our previous paper following Tits-type alternative: if X is toric affine variety G subgroup Aut(X) generated by finite set unipotent subgroups normalized acting torus then either contains nonabelian free or algebraic group. In present we extend latter result to any surface collection subgroups. It occurs metabelian

Digital cohomology groups of certain minimal surfaces
In this study, we compute simplicial cohomology groups with different coefficients of a connected sum of certain minimal simple surfaces by using the universal coefficient theorem for cohomology groups. The method used in this paper is a different way to compute digital cohomology groups of minimal simple surfaces. We also prove some theorems related to degree properties of a map on digital sph...
متن کاملTits alternative for 3-manifold groups
Let M be an irreducible, orientable, closed 3-manifold with fundamental group G. We show that if the pro-p completion Ĝp of G is infinite then G is either soluble-by-finite or contains a free subgroup of rank 2.
متن کاملThe Tits alternative for generalised tetrahedron groups
A generalised tetrahedron group is the colimit of a triangle of groups whose vertex groups are generalised triangle groups and whose edge groups are finite cyclic. We prove an improved Spelling Theorem for generalised triangle groups which enables us to compute the precise Gersten-Stallings angles of this triangle of groups, and hence obtain a classification of generalised tetrahedron groups ac...
متن کاملHigher Tits indices of linear algebraic groups
Let G be a semisimple algebraic group over a field k. We introduce the higher Tits indices of G as the set of all Tits indices of G over all field extensions K/k. In the context of quadratic forms this notion coincides with the notion of the higher Witt indices introduced by M. Knebusch and classified by N. Karpenko and A. Vishik. We classify the higher Tits indices for exceptional algebraic gr...
متن کاملTits p-indexes of semisimple algebraic groups
The first author has recently shown that semisimple algebraic groups are classified up to motivic equivalence by the local versions of the classical Tits indexes over field extensions, known as Tits p-indexes. We provide in this article the complete description of the values of the Tits p-indexes over fields. From this exhaustive study, we also deduce criteria for motivic equivalence of semisim...
