About extension of homeomorphisms over zero-dimensional homogeneous spaces
S. V. Medvedev South Ural State University
Abstract:
Let X be a zero-dimensional homogeneous space satisfying the first axiom of countability. We prove the theorem about an extension of a homeomorphism g:A→B to a homeomorphism f:X→X, where A and B are countable disjoint compact subsets of the space X. If, additionally, X is a non-pseudocompact space, then the homeomorphism g is extendable to a homeomorphism f:X→X∖A.
Keywords:
homogeneous space; homeomorphism; first axiom of countability; pseudocompact space.
