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