Oriented and Unitary Equivariant Bordism of Surfaces

Explore a 51-minute lecture on oriented and unitary equivariant bordism of surfaces presented by Bernardo Uribe from Universidad del Norte at the University of Miami. Delve into the collaborative research findings of Uribe, Angel, Segovia, and Samperton, who have successfully determined the torsion part of both equivariant oriented and unitary bordism groups. Learn about the key result: the calculation of the obstruction class for a surface with free action to bound equivariantly. Gain insights into this obstruction class and discover an explicit group where the invariant is non-trivial, enhancing your understanding of advanced topics in algebraic topology and geometric group theory.
