This invariant is preserved under cut-and-paste operations by contact gluing maps of Honda, Kazez, and Mati\u0107. However, these maps are difficult to compute in practice, even in simple cases. Our work reinterprets these maps in terms of gluing maps in bordered sutured Floer theory defined by Zarev. In particular, we establish Zarev\u2019s conjecture that his pairing on sutured Floer homology is equivalent to the contact gluing map. As an application, we directly compute Honda\u2013Kazez\u2013Mati\u0107 maps in some interesting cases. This project is joint with Ryan Leigon.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Geometry\u00a0&amp; Topology Seminar Speaker:\u00a0Federico Salmoiraghi (Technion) Topic:\u00a0Equivalence of contact gluing maps in sutured Floer homology.
