WebDec 9, 2013 · These introductory lectures show how to define finite type invariants of links and 3-manifolds by counting graph configurations in 3-manifolds, following ideas of Witten and Kontsevich. The linking number is the simplest finite type invariant for 2-component links. It is defined in many equivalent ways in the first section. As an important example, …

WebSecondly, we define finite type invariants directly on knotoids, by extending knotoid invariants to singular knotoid invariants via the Vassiliev skein relation. Then, for spherical knotoids we show that there are non-trivial type-1 invariants, in contrast with classical knot theory where type-1 invariants vanish. WebIn Sect. 3.4 we study the map from knots (in S 3) to ZHS defined by mapping a knot K in S 3 to the ZHS S K,+I 3 obtained by +1 surgery on K (see [Ro], and Sect. 3.1). We show (proposition 3.12) that type 5m + 1 invariants of ZHS map to type 4m invariants of …
