Symplectic Excision and Distance Rigidity

Yoel Groman

We consider various notions of completeness in symplectic topology and ask two related questions. Does a complete open symplectic manifold remain complete after excising a subset?…

Boundary Depth and Deformations of Symplectic Cohomology

Yoel Groman

We study the relation between two versions of symplectic cohomology associated to a Liouville domain $D$ embedded in a symplectic manifold $M$ : the ambient version $S C_{M}^{*} (D)$ defi…

Almost toric fibrations on symplectic blow ups

Pranav Chakravarthy, Yoel Groman

Given a symplectic 4-manifold with an almost toric fibration and a symplectic ball embedding whose image under the moment map is contained in an affine convex set R, we produce a s…

Almost toric fibrations on K3 surfaces via degenerations

Pranav Chakravarthy, Yoel Groman

For Kähler K3 surfaces we consider Kulikov models of type III tamed by a symplectic form. Our main result shows that the generic smooth fiber admits an almost toric fibration over…
