Correction terms, $Z_{2}$ --Thurston norm, and triangulations

Yi Ni, Zhongtao Wu

We show that the correction terms in Heegaard Floer homology give a lower bound to the the genus of one-sided Heegaard splittings and the $Z_{2}$ --Thurston norm. Using a resu…

Four-ball genus bounds and a refinement of the Ozsvath-Szabo tau-invariant

Jennifer Hom, Zhongtao Wu

Based on work of Rasmussen, we construct a concordance invariant associated to the knot Floer complex, and exhibit examples in which this invariant gives arbitrarily better bounds…
