Bordered contact invariants and half Giroux torsion
Hyunki Min, Konstantinos Varvarezos
We show that there exist infinitely many closed contact 3-manifolds containing half Giroux torsion along a separating torus whose contact invariants do not vanish. This provides co…

On contact invariants in bordered Floer homology
Hyunki Min, Konstantinos Varvarezos
In this paper, we define contact invariants in bordered sutured Floer homology. Given a contact 3-manifold with convex boundary, we apply a result of Zarev (arxiv:1010.3496) to der…
