Knots and Primes
OSAZ SS 14 18. M¨arz 2014
This semester we will work out an analogy between knot and number theory, our principal reference being the book of Morishita [Mor12]. This analogy can be traced back to Gauss and his work on quadratic residues and the notion of the linking number, which he found working on electrody- namics. From then on both areas branched out independently and it was not before the geometrization of number theory (scheme theory) that the gap bet- ween both areas could be bridged.
We will start to recollect some basic notions and results from algebraic topo- logy and number theory in the first three talks. The fourth talk will present fundamental analogies between 3-manifolds and number rings, knots and pri- mes which are the basis for the remaining talks. From talk five on, further analogies will be presented and a kind of dictionary will be developed, translating between number and knot theory.
