I intend to show some correspondence between some aspects of mixed Hodge structures of isolated singularities and classical knot invariants, like Alexander polynomial and signature of a knot. This correspondence is quite known for the links of plane curve singularities. In general case it allows to generalise some knot invariants. This is joint work with A. Nemethi from Renyi Institute.
