Simplicial descent for Chekanov-Eliashberg dg-algebras
Johan Asplund
4:00pm|Fine 314 and Remote Access

The Chekanov-Eliashberg dg-algebra gives an invariant of Legendrian submanifolds up to Legendrian isotopy and can be used to compute wrapped Fukaya categories of Weinstein manifolds. In this talk we introduce a type of surgery decomposition of...

Contact non-squeezing via selective symplectic homology
Igor Uljarević
9:15am|Remote Access

I will introduce a new version of symplectic homology that resembles the relative symplectic homology and that is related to the symplectic homology of a Liouville sector. This version, called selective symplectic homology, is associated with a...

Three-dimensional Anosov flows and non-Weinstein Liouville domains.
Thomas Massoni
4:00pm|Simonyi 101 and Remote Access

An Anosov flow $\Phi$ on a closed $3$-manifold $M$ gives rise to a non-Weinstein Liouville structure on $V:=[-1,1] \times M$. Building upon the work of Hozoori, we establish a homotopy correspondence between Anosov flows and certain pairs of contact...
