Borsuk-Ulam type theorems for manifolds
Oleg Rustumovich Musin · Proceedings of the American Mathematical Society · 2011
This paper establishes a Borsuk-Ulam type theorem for PL- manifolds with a finite group action, depending on the free equivariant cobordism class of a manifold. In particular, necessary and sufficient conditions are considered for a manifold with a free involution to be of Borsuk-Ulam type.
