TOPOLOGY SEMINAR: Filtrations of Smooth concordance classes of topologically slice knots
by Tim Cochran (Rice) in HB 427
The n-solvable filtration of the smooth knot (or string link) concordance group, C, has provided a framework for many recent advances in the study of knot concordance. However it is useless for studying the subgroup, T , of topologically slice knots. We (joint with S. Harvey and P. Horn) define and investigate new highly non-trivial filtrations of C and give evidence that they induce non-trivial filtrations of T.
