  journal={arXiv: Differential Geometry},
Every compact aspherical Riemannian manifold admits a canonical series of orbibundle structures with infrasolv fibers which is called its infrasolv tower. The tower arises from the solvable radicals of isometry group actions on the universal covers. Its length and the geometry of its base measure the degree of continuous symmetry of an aspherical Riemannian manifold. We say that the manifold has large symmetry if it admits an infrasolv tower whose base is a locally homogeneous space. We…

Locally homogeneous aspherical Sasaki manifolds
Let $G/H$ be a contractible homogeneous Sasaki manifold. A compact locally homogeneous aspherical Sasaki manifold $\Gamma\big\backslash G/H$ is by definition a quotient of $G/H$ by a discrete uniform


Compact Clifford-Klein forms of symmetric spaces
We recall that a Riemannian manifold X is symmetric, in the sense of Cartan, if it is connected and if every point x E X is an isolated fixed point of an involutive isometry s, of X. The map s, is
The Group of Isometries of a Riemannian Manifold
In the classical theory of groups of motions (isometries) of a Riemannian space,1 neither "whole" groups nor "whole" spaces were ever considered, but only "group germs" and spaces in the neighborhood
Isometries, rigidity and universal covers
The goal of this paper is to describe all closed, aspherical Riemannian manifolds M whose universal covers M have have a nontrivial amount of symmetry. By this we mean that Isom(M) is not discrete.
Infra-solvmanifolds and rigidity of subgroups in solvable linear algebraic groups
Abstract We give a new proof that compact infra-solvmanifolds with isomorphic fundamental groups are smoothly diffeomorphic. More generally, we prove rigidity results for manifolds which are
On the first Betti number of a constant negatively curved manifold
constant negatively curved n-dimensional manifolds with arbitrarily large first Betti number. In fact we show that any constant negatively curved manifold whose fundamental group is an arithmetic
On fundamental groups of complete affinely flat manifolds
First some definitions. A group I is virtually polycyclic if it has a subgroup r, of finite index which is polycyclic, that is, admits a finite composition series r, 3 r, 3 -1.3 r, = (1) so that each

On the Existence of Slices for Actions of Non-Compact Lie Groups
If G is a topological group then by a G-space we mean a completely regular space X together with a fixed action of G on X. If one restricts consideration to compact Lie groups then a substantial
