The Borsuk-Ulam theorem for closed 3-dimensional manifolds having Nil Geometry

A. Bauval, D. L. Gonçalves, C. Hayat

Let M be a closed, connected 3-manifold which admits Nil geometry, we determine all free involutions on M and the Borsuk-Ulam index of .

The Borsuk-Ulam theorem for the Seifert manifolds having flat geometry

A. Bauval, D. L. Gonçalves, C. Hayat

Let M be a Seifert manifold which belongs to the geometry Flat. In this work we determine all the free involutions τ on M, and the Borsuk-Ulam indice of (M,τ).

Classifications of special double-coverings associated to a non-orientable surface

Anne Bauval, Claude Hayat

This paper investigates some actions "à la Johnson" on the set, denoted by , of Spin-structures which are interpreted as special double-coverings of a trivial fibra…
