Stein traces and characterizing slopes
Roger Casals, John Etnyre, Marc Kegel
We show that there exists an infinite family of pairwise non-isotopic Legendrian knots in the standard contact 3-sphere whose Stein traces are equivalent. This is the first example…
Positroid Links and Braid varieties
Roger Casals, Eugene Gorsky, Mikhail Gorsky +1
We study braid varieties and their relation to open positroid varieties. We discuss four different types of braids associated to open positroid strata and show that their associate…
Dynamical Quantization of Contact Structures
Roger Casals, Gabriel Herczeg, Andrew Waldron
We construct a dynamical quantization for contact manifolds in terms of a flat connection acting on a Hilbert tractor bundle. We show that this contact quantization, which is indep…
Branched covering simply-connected 4-manifolds
David Auckly, R. Inanc Baykur, Roger Casals +3
We prove that any closed simply-connected smooth 4-manifold is 16-fold branched covered by a product of an orientable surface with the 2-torus, where the construction is natural wi…
Braid Loops with infinite monodromy on the Legendrian contact DGA
Roger Casals, Lenhard Ng
We present the first examples of elements in the fundamental group of the space of Legendrian links in the standard contact 3-sphere whose action on the Legendrian contact DGA is o…
