The Borsuk-Ulam property for homotopy classes of maps between the torus and the Klein bottle

Daciberg Lima Gonçalves, John Guaschi, Vinicius Casteluber Laass

Let $M$ be a topological space that admits a free involution $\tau$, and let $N$ be a topological space. A homotopy class $\beta \in [M,N]$ is said to have {\it the Borsuk-Ulam property…
