Diffeomorphisms of Manifolds with Finite Fundamental Group
We show that the group 3i{M) of pseudoisotopy classes of diffeomorphisms of a manifold of dimension > 5 and of finite fundamental group is commensurable to an arithmetic group. As a result n0{DiffM) is a group of finite type. Let M be an «-dimensional closed smooth manifold, where n > 5, and let DiffM be the group of diffeomorphisms of M. The space DiffM (it is a topological space with the C°°-...
متن کاملThe Rational Symmetric Signature of Manifolds with Finite Fundamental Group
defined by (a, fl)o = (ctujl)[M] is a non-singular (l)k-symmetric bilinear pairing. The isometry class of the rational intersection form is determined by the rank if k is odd and by the rank and signature if k is even. We wish to make a corresponding analysis of the equivariant intersection form in the case where M is the total space of a finite G-cover. Let G be a finite group and w: G + { f l...
متن کاملClassification of Partially Hyperbolic Diffeomorphisms in 3-manifolds with Solvable Fundamental Group
A classification of partially hyperbolic diffeomorphisms on 3-dimensional manifolds with (virtually) solvable fundamental group is obtained. If such a diffeomorphism does not admit a periodic attracting or repelling two-dimensional torus, it is dynamically coherent and leaf conjugate to a known algebraic example. This classification includes manifolds which support Anosov flows, and it confirms...
متن کاملThe Fundamental Group of S1-manifolds
We address the problem of computing the fundamental group of a symplectic S-manifold for non-Hamiltonian actions on compact manifolds, and for Hamiltonian actions on non-compact manifolds with a proper moment map. We generalize known results for compact manifolds equipped with a Hamiltonian S-action. Several examples are presented to illustrate our main results.
