First order rigidity of homeomorphism groups of manifolds

Abstract

For every compact, connected manifold MM, we prove the existence of a sentence ϕM\phi_M in the language of groups such that the homeomorphism group of another compact manifold NN satisfies ϕM\phi_M if and only if NN is homeomorphic to MM. We prove the analogous statement for groups of homeomorphisms preserving an Oxtoby--Ulam probability measure.
