TOPOLOGY SEMINAR: Infection and the n-solvable filtration
by Bridget Franklin (Rice Math Dept.) in HB 427
I will discuss the choices involved in an infection operation of a knot and how these choices affects the concordance class of the output knot. In particular, I will give conditions such that nonconcordant knots are produced using identical input knots but varying infection curves. The analysis involves methods using the n-solvable filtration, the Blanchfield linking form, and von-Neumann rho-invariants. Definitions and previous results will be given as an introduction to these techniques. Host Department: Rice University-Mathematics
