چکیده

Let X 1 , X 2 be mixing connected algebraic dynamical systems with the Descending Chain Condition. We show that every equivariant continuous map X 1 → X 2 is affine (that is, X 2 is topologically rigid) if and only if the system X 2 has finite topolog-ical entropy.

Finite entropy characterizes topological rigidity on connected groups

Let X1, X2 be mixing connected algebraic dynamical systems with the descending chain condition. We show that every equivariant continuous map X1 → X2 is affine (that is, X2 is topologically rigid) if and only if the system X2 has finite topological entropy.

F eb 2 00 6 MOMENT - ANGLE COMPLEXES , MONOMIAL IDEALS , AND MASSEY PRODUCTS GRAHAM

Associated to every finite simplicial complex K there is a “moment-angle” finite CW-complex, ZK ; if K is a triangulation of a sphere, ZK is a smooth, compact manifold. Building on work of Buchstaber, Panov, and Baskakov, we study the cohomology ring, the homotopy groups, and the triple Massey products of a moment-angle complex, relating these topological invariants to the algebraic combinatori...

Entropy operator for continuous dynamical systems of finite topological entropy

In this paper we introduce the concept of entropy operator for continuous systems of finite topological entropy. It is shown that it generates the Kolmogorov entropy as a special case. If $phi$ is invertible then the entropy operator is bounded with the topological entropy of $phi$ as its norm.

We study diagrams associated with a finite simplicial complex K, in various algebraic and topological categories. We relate their colimits to familiar structures in algebra, combinatorics, geometry and topology. These include: right-angled Artin and Coxeter groups (and their complex analogues, which we call circulation groups); Stanley-Reisner algebras and coalgebras; Davis and Januszkiewicz's ...

6 F eb 2 00 5 Universal lattices and property τ

We prove that the universal lattices – the groups G = SLd(R) where R = Z[x1, . . . , xk], have property τ for d ≥ 3. This provides the first example of linear groups with τ which do not come from arithmetic groups. We also give a lower bound for the τ -constant with respect to the natural generating set of G. Our methods are based on bounded elementary generation of the finite congruence images...
