Awning

,Messung der Anlegeman?ver von Tankern,em that Alexander polynomial one knots are topologically slice. This paper develops null-homologous twisting operations as a tool for studying the algebraic genus and, consequently, for bounding the topological slice genus above. As applications we give new upper bounds on the algebraic genera of torus knots and satellite knots.

Die H?fen in Bremerhaven 1950 –1963s numerous applications include the study of unlinking numbers and link concordance. In this survey, we recall the three and four dimensional definitions of σ., list its main properties and applications, and give comprehensive references for the proofs of these statements.

The first main result is that two .-complexes with the same strongly minimal model are homotopy equivalent if and only if their intersection pairings are isometric. If . ≤ 2 every such complex has a st

Given a PL manifold Y of dimension n, this is a decomposition of Y into . PL submanifolds. We show that every smooth, oriented, compact 5-manifold admits a smooth trisection. F
