Homotopy equivalence is a weaker version of equivalence than homeomorphism. A homotopy equivalence can be thought of as a continuous squishing and stretching (i.e. a deformation) of the space. Here are some examples of homotopy equivalences which are and are not homeomorphisms. Homomorphism deals...

We introduce several homotopy equivalence relations for proper holomorphic mappings between balls. We provide examples showing that the degree of a rational proper mapping between balls (in positive codimension) is not a homotopy invariant. In domain dimension at least 2, we prove that the set of ...
