Conjecture on morphisms from punctured-surface homeomorphism groups
Conjecture on morphisms from punctured-surface homeomorphism groups
Let be a closed surface, let be an open disc in , and write for the surface obtained by removing . Let be the identity component of the group of homeomorphisms of whose support is contained in the interior of . The punctured-surface morphism conjecture. Every group morphism
is induced by an inclusion of in . The conjecture concerns the rigidity of morphisms between homeomorphism groups of surfaces and is presented as an attainable problem; no resolution is given in the source.
