An introduction to knot concordance (Paolo Aceto)

Séminaire « Doctorants et postdoctorants »
Kampé de Fériet (M2, 1er étage)
After a brief introduction to the basics of knot theory we introduce the most basic concepts of knot concordance such as the notion of sliceness for a knot and some elementary properties of the concordance group. We discuss in detail several simple examples and state some open problems including the so called slice-ribbon conjecture.
