Automatic Continuity in Homeomorphism Groups of Compact 2-manifolds
We show that any homomorphism from the homeomorphism group of a compact 2-manifold, with the compact-open topology, or equivalently, with the topology of uniform convergence, into a separable topological group is automatically continuous.
متن کاملEnds of groups and compact Kähler manifolds
Asking that a manifold admit a Kähler structure places swingeing restrictions on its topology. The best-known illustration of this comes from Hodge theory: one knows that when a complex structure on a manifold has a compatible symplectic structure, the decomposition of forms into Hodge types descends to cohomology, with far-reaching consequences. However, this turns out to be just the tip of th...
متن کاملOn Covering Translations and Homeotopy Groups of Contractible Open N-manifolds
This paper gives a new proof of a result of Geoghegan and Mihalik which states that whenever a contractible open n-manifold W which is not homeomorphic to Rn is a covering space of an n-manifold M and either n ≥ 4 or n = 3 and W is irreducible, then the group of covering translations injects into the homeotopy group of W .
متن کاملArithmetic Groups Acting on Compact Manifolds
In this note we announce results concerning the volume preserving actions of arithmetic subgroups of higher rank semisimple groups on compact manifolds. Our results can be considered as the first rigidity results for homomorphisms of these groups into diffeomorphism groups and show a sharp contrast between the behavior of actions of these groups and actions of free groups. Let G be a connected ...
متن کاملIsometric actions of Heisenberg groups on compact Lorentz manifolds
We prove results toward classifying compact Lorentz manifolds on which Heisenberg groups act isometrically. We give a general construction, leading to a new example, of codimension-one actions—those for which the dimension of the Heisenberg group is one less than the dimension of the manifold. The main result is a classification of codimension-one actions, under the assumption they are real-ana...
