Equivariant rational concordance of strongly invertible knots

speaker: Oğuz Şavk (CNRS)

abstract: In this talk, I will present joint work with Alessio Di Prisa on the study of equivariant rational concordance of strongly invertible knots. I will discuss the new theory with several explicit constructions (with a refinement of Kawauchi's theorem) and obstructions (with a refinement of the Fox-Milnor condition). I will also introduce the equivariant rational concordance group and discuss its relations with the other concordance groups.
