All frame-spun knots are slice
Greg Friedman
Frame-spun knots are constructed by spinning a knot of lower dimension about a framed submanifold of S^n. We show that all frame-spun knots are slice (null-cobordant).
Alexander polynomials of non-locally-flat knots
Greg Friedman
We generalize the classical study of Alexander polynomials of smooth or PL locally-flat knots to PL knots that are not necessarily locally-flat. We introduce three families of gene…
Stratified fibrations and the intersection homology of the regular neighborhoods of bottom strata
Greg Friedman
In this paper, we develop Leray-Serre-type spectral sequences to compute the intersection homology of the regular neighborhood and deleted regular neighborhood of the bottom stratu…
Intersection Alexander polynomials
Greg Friedman
By considering a (not necessarily locally-flat) PL knot as the singular locus of a PL stratified pseudomanifold, we can use intersection homology theory to define intersection Alex…
