Complete invariant for fused links (Timur Nasybullov, Universita di Bologna)

One of the most important problems in knot theory is the knot recognition problem, is determining the equivalence of two knots. A complete algorithmic solution of this problem exists but it has unknown complexity. Virtual knot theory is a generalization of classical knot theory which was introduced by L.Kauffman in 1999. For virtual knots it is also very important to solve the knot recognition problem. In the talk I am going to introduce one simplification of classical and virtual knot theories called fused knot theory and solve the knot recognition problem for fused links in polynomial time.
