报告摘要：
As an extension of classical knot theory, virtual knot theory was introduced by Louis Kauffman in the end of last century. Several classical knot invariants have been extended to virtual knot invariants, such as knot group/quandle, Alexander polynomial, Jones polynomial. In this talk, I will give an introduction to index type invariants of virtual knots. Several constructions and applications will be discussed.
