报告摘要:

As an extension of classical knot theory, virtual knot theory was introduced by Louis Kauffman in 1990s. Virtual knot theory studies the stable embeddings of one sphere in thickened surfaces of higher genera. In this talk, I will give a quick introduction to virtual knots. Then I will focus on the index type invariants of virtual knots, which were developed vigorously over the last decade.
