Rigidity of matrix group actions on CAT(0) spaces with possible parabolic isometries and uniquely arcwise connected spaces

Shengkui Ye

It is well-known that $SL_{n} (Q_{p})$ acts without fixed points on an $(n - 1)$ -dimensional $CAT (0)$ space (the affine building). We prove that $n - 1$ is th…

On the bounded index property for products of aspherical polyhedra

Shengkui Ye, Qiang Zhang

A compact polyhedron $X$ is said to have the Bounded Index Property for Homotopy Equivalence (BIPHE) if there is a finite bound $B$ such that for any homotopy equivalence…

Intersections of subcomplexes in non-positively curved 2-dimensional complexes

Feng Ji, Shengkui Ye

Let $X$ be a contractible $2$ -complex which is a union of two contractible subcomplexes $Y$ and $Z .$ Is the intersection $Y \cap Z$ contractible as well? In this note, we prove that…

Piecewise linear actions and Zimmer's program

Shengkui Ye

We consider Zimmer's program of lattice actions on surfaces by PL homomorphisms. It is proved that when the surface is not the torus or Klein bottle the action of any finite-index…
