Cylindrical contact homology of links of simple singularities (V2)

Leo Digiosia

We compute the cylindrical contact homology of the links of the simple singularities. These manifolds are contactomorphic to $S^{3} / G$ for finite subgroups $G \subset SU (2)$ . We…

A contact McKay correspondence for links of simple singularities

Leo Digiosia, Jo Nelson

We compute the cylindrical contact homology of the links of the simple singularities. These manifolds are contactomorphic to $S^{3} / G$ for finite subgroups $G \subset S U (2)$ . We pertu…

Symplectic embeddings of four-dimensional polydisks into half integer ellipsoids

Leo Digiosia, Jo Nelson, Haoming Ning +2

We obtain new sharp obstructions to symplectic embeddings of four-dimensional polydisks $P (a, 1)$ into four-dimensional ellipsoids $E (b c, c)$ when $1 \leq a < 2$ and $b$ is a half-integ…
