Title: Perfect pairings of motivically filtered trace invariants

Abstract: Perfect pairings of trace invariants encode various dualities (such as local Tate duality in Galois cohomology), as well as the existence of Gysin maps. I will discuss joint work in progress with Devalapurkar and Rognes regarding the generality in which these perfect pairings can be lifted to the synthetic category.
