Course description and aims

The main subject of this course is the theory of quantum cohomology. In this course, we start with the moduli space of stable maps to see the outline of the construction of the Gromov-Witten invariants, and then introduce their fundamental properties. After that, we discuss the relationship between the structure of quantum cohomology rings and integrable systems via the J-functions. If time permits, we also see the topics on the quantum K-theory etc.
The developments of the topological field theory in the particle physics at the end of the 20th century provide a new approach to the classical enumerative algebraic geometry, which is now known as the Gromov-Witten theory or the theory of quantum cohomology. The theory of quantum cohomology rings was established in early 90s mainly to understand the Mirror Symmetry phenomenon, and it has been playing important roles in the geometry of the field theory over since. The main aim of this course is to make students understand the relationship between the quantum cohomology ring of the flag variety and the Toda system.
