Baum-Dąbrowski-Hajac topological Borsuk-Ulam conjecture
Baum-Dąbrowski-Hajac topological Borsuk-Ulam conjecture
Let be a compact Hausdorff space with a free action of a nontrivial compact group . Equip the join with the diagonal action. Baum-Dąbrowski-Hajac's topological Borsuk-Ulam conjecture. There is no equivariant map
This generalizes the Borsuk-Ulam theorem from antipodal actions on spheres to free actions of compact groups on compact Hausdorff spaces. The source gives no resolution status for this conjecture.
