Description: |
For each knot in the 3-sphere it is possible to construct an infinite family of topological invariants, the cyclic branched covers of the knot. After describing how these invariants are constructed, I will try to give an overview of the problem of determining how strong these invariants are. A variety of examples will be discussed in order to contextualise the problem and to underline its difficulty. I shall also discuss several known results, focusing in particular on the case of hyperbolic knots.
