Ryan Stees (U. of Virginia) - Triple linking and rational homology cobordism

Speaker: Ryan Stees

Abstract: In this talk, we will study the recently-defined Freedman-Krushkal triple torsion linking form in the context of 3-dimensional topological rational homology cobordism. After providing some background, we will give a new condition under which this form vanishes. Time permitting, we will discuss some related open questions.
