Thematic program "New Trends in Topology"

February 1 – June 30, 2022

There were several far-reaching conceptual developments in topology at the turn of the century. In the late 1980’s – early 1990’s, a spectacular progress in the theory of knots and 3-dimensional manifolds was made by the Fields medalists E. Witten and V. Jones followed by the work of N. Reshetikhin, V. Turaev, O. Viro and others who related this area of topology to the theory of quantum groups. As a result, a new mathematical field was born, the topological quantum field theory.

In parallel to the appearance of the topological quantum field theory, there emerged a theory of Gromov-Witten invariants, under the influence of implantation of pseudo-holomorphic curve technique into symplectic geometry by M. Gromov and the holomorphic curve counting into quantum 2-dimensional gravity by E. Witten. This had led, in particular, to the Kontsevich-Manin theory of quantum cohomology and a breakthrough in enumerative geometry.

These new research areas are not only linked by the time of their appearance and the string theory as a common root, but also by deep relations between the techniques and underlying algebraic structures. The very recent developments in Gromov-Witten theory brought to light direct bridges between enumerative geometry of open strings and the theory of knot invariants. This program is devoted to a number of the most active areas of these research fields.
