Symplectic Embeddings of Hirzebruch Surfaces
Nicole Magill
4:00pm|Simonyi 101 and Remote Access

The four dimensional ellipsoid embedding function of a toric symplectic manifold M measures when a symplectic ellipsoid embeds into M. It generalizes the Gromov width and ball packing numbers. This function can have a property called an infinite...

David White (North Carolina State University):  Symplectic Instanton Homology of Knots and Links in 3-manifolds

Powerful homology invariants of knots in 3-manifolds have emerged from both the gauge-theoretic and the symplectic kinds of Floer...

Non-standard Contact Structures on Spheres and Applications
Agustin Moreno
9:45am|Simonyi Hall 101 and Remote Access

In this talk, I will describe the construction of contact structures on higher-dimensional spheres with exotic fillability properties. These can then me implemented on more general manifolds via connected sum, yielding a host of exotic higher...

Hypersurface Singularities and Spectral Invariants
Yusuke Kawamoto
9:15am|Remote Access

We discuss the relation between hypersurface singularities (e.g. ADE, $\widetilde{E}_{6},\widetilde{E}_{7},\widetilde{E}_{8}$, etc) and spectral invariants, which are symplectic invariants coming from Floer theory.

From Embedded Contact Homology to Surface Dynamics
Jo Nelson
4:00pm|Rubenstein Commons | Meeting Room 5

I will discuss work in progress with Morgan Weiler on knot filtered embedded contact homology (ECH) of open book decompositions of S^3 along T(2,q) torus knots to deduce information about the dynamics of symplectomorphisms of the genus (q-1)/2 pages...
