A Review of Heegaard Floer Homology Contact Invariant
Merve Seçgin
TED University, Turkey
Özet : In the early 2000's, Ozsvath and Szabo defined powerful algebraic tools for low dimensional objects, specifically for closed 3-manifolds, called Heegaard Floer Homology. We will introduce and review the contact invariant which is an element of the (hatted) Heegaard Floer Homology group of a closed contact 3-manifold. It gives a criterion for tightness and Stein fillability of the given contact structure.
