Computing Heegaard Floer invariants of closed contact 3-manifolds from open books
Cagatay Kutluhan, Gordana Matic, Jeremy Van Horn-Morris +1
We present two SageMath programs that build on and improve upon Sucharit Sarkar's hf-hat. Given an abstract open book and a collection of pairwise disjoint properly embedded arcs o…
An exotic 5RP^2 in the 4-sphere
Gordana Matić, Ferit Öztürk, Javier Reyes +2
We show an example of an embedded copy of 5RP^2 in the four-sphere which is topologically standard but smoothly knotted, i.e. smoothly not isotopic to the standard embedding.
Algorithms for Computing Invariants of Trisected Branched Covers
Patricia Cahn, Gordana Matic, Benjamin Ruppik
We give diagrammatic algorithms for computing the group trisection, homology groups, and intersection form of a closed, orientable, smooth 4-manifold, presented as a branched cover…
Filtering the Heegaard Floer contact invariant
Cagatay Kutluhan, Gordana Matic, Jeremy Van Horn-Morris +1
We define an invariant of contact structures in dimension three from Heegaard Floer homology. This invariant takes values in the set . It is zero…
Algebraic torsion via Heegaard Floer homology
Cagatay Kutluhan, Gordana Matic, Jeremy Van Horn-Morris +1
We outline Hutchings's prescription that produces an ECH analog of Latschev and Wendl's algebraic -torsion in the context of , a variant of ECH used in a proof of the isomo…
Contact structures, sutured Floer homology and TQFT
Ko Honda, William H. Kazez, Gordana Matic
We describe the natural gluing map on sutured Floer homology which is induced by the inclusion of one sutured manifold (M',Γ') into a larger sutured manifold (M,Γ), together with a…
