%0 Journal Article %T A topologically minimal, weakly reducible, unstabilized Heegaard splitting of genus three is critical %A Jungsoo Kim %J Mathematics %D 2014 %I arXiv %X Let (V,W;F) be a weakly reducible, unstabilized, genus three Heegaard splitting in an orientable, irreducible 3-manifold M. In this article, we prove that either the disk complex D(F) is contractible or F is critical. Hence, the topological index of F is two if F is topologically minimal. %U http://arxiv.org/abs/1402.4253v4
