Isomorphism of Graphs Which are k-Separable*
A polynomial time algorithm for testing isomorphism of graphs which are pairwise k-separable for fixed k is given. The pairwise k-separable graphs are those graphs where each pair of distinct vertices are k-separable. This is a natural generalization of the bounded valence test of Luks.The subgroup of automorphisms of a hypergraph whose restriction to the vertices is in a given group, for fixed...

متن کاملA Strong Boundedness Result for Separable Rosenthal Compacta
Our main result is a strong boundedness result for the class of separable Rosenthal compacta (that is, separable compact subsets of the first Baire class – see [ADK] and [Ro2]) on the Cantor set having a uniformly bounded dense sequence of continuous functions. We shall denote this class by SRC. The phenomenon of strong boundedness, which was first touched by A. S. Kechris and W. H. Woodin in [...
متن کاملSeparable Zero-dimensional Spaces Which Are Continuous Images of Ordered Compacta
A structure theorem is proved about separable zero-dimensional spaces which are continuous images of ordered compacta and it is shown that not all spaces in this class are orderable themselves.
متن کاملBianchi Groups Are Conjugacy Separable
We prove that non-uniform arithmetic lattices of SL2(C) and in particular the Bianchi groups are conjugacy separable. The proof based on recent deep results of Agol, Long, Reid and Minasyan.
