On the cohomology of discrete abelian group actions
Generalizing a result of Depauw, we prove that the geometric cohomology groups for a Z d action are in any dimension isomorphic to the Feldman-Moore cohomology groups rsp. the algebraic group cohomology groups. This result holds in the smooth, topological or measurable category and for general Polish groups as coeecient groups.
متن کاملSome Examples of Discrete Group Actions on Aspherical Manifolds
We construct two classes of examples of a virtually torsionfree group G acting properly and cocompactly on a contractible manifold X. In the first class of examples the universal space for proper actions, EG, has no model with finitely many orbits of cells. The reason is that the centralizers of certain finite subgroups of G will not have finitetype classifying spaces. In the second class of ex...
متن کاملHomologically Trivial Group Actions on 4-Manifolds
In this paper we investigate pseudofree homologically trivial actions of arbitrary finite groups on simply connected 4-manifolds. It turns out that there are surprisingly strong restrictions on the groups and on the actions, especially when one considers the fact that any finite group can act, even freely, on some simply connected 4-manifold. Recall that a finite group action is free if no nont...
متن کاملAlgebraic Realization of Manifolds with Group Actions
Let G be a compact Lie group and M a closed smooth G manifold. With some restrictions on G or on the isotropy groups of the action we show that M is algebraically realized, i. e., there exists a non-singular real algebraic G variety which is equivariantly diffeomorphic to M .
متن کاملGROUP ACTIONS ON SPIN MANIFOLDS(i)
A generalization of the theorem of V. Bargmann concerning unitary and ray representations is obtained and is applied to the general problem of lifting group actions associated to the extension of structure of a bundle. In particular this is applied to the Poincare group ? of a Lorentz manifold M. It is shown that the topological restrictions needed to lift an action in ? are more stringent than...
