The Borsuk-Ulam property for homotopy classes of selfmaps of surfaces of Euler characteristic zero

Daciberg Lima Gonçalves, John Guaschi, Vinicius Casteluber Laass

Let M and N be topological spaces such that M admits a free involution $\τ$. A homotopy class $\beta$ $\in$ [M, N ] is said to have the Borsuk-Ulam property with respect to $\τ$ if for…
