A cellular map between nonhomeomorphic polyhedra whose nondegeneracy set is a null sequence
James P. Henderson · Proceedings of the American Mathematical Society · 1982
A cellular map between nonhomeomorphic polyhedra whose nondegeneracy set consists of a null sequence of cellular sets is constructed. The construction begins with Daverman’s example of a cellular map between nonhomeomorphic polyhedra and uses an amalgamation technique.
