Quantum cohomology and quantum differential equation

In that talk, follow the sections 2.1.2. and 2.1.4. of [5]. Introduce the (big) quantum cohomology on a variety with no odd cohomology and the WDVV equation. Compute the quantum product for P 2. Introduce the quantum differential equation and derive a fundamental set of solutions. The map S(Ti) = si as defined in 2.1.4 will play an important role in the sequel so should be discussed.
