We find lower bounds for the higher-order genera in terms of certain von Neumann ρρ-invariants, which we call higher-order signatures. The higher-order genera o…

In this note we study the topology of 3-dimensional initial data sets with horizons of a sort associated with asymptotically locally anti-de Sitter spacetimes.

In 1980 J. Powell proposed that five specific elements sufficed to generate the Goeritz group of any Heegaard splitting of S3S^3, extending work of Goeritz on genus 22 splittings. Here we prove that Powell's conjecture was correct for splittings of genus 33 as well, and discuss a framework for deciding the truth of t…
