In the first half of the talk I shall present a new algebraic proof of a result of Deligne-Illusie about the degeneration of the Hodge-de Rham spectral sequence. The idea is to reduce the main technical point of their proof to a question about the...

In this talk I'll describe a proof of Klemm, Maulik, Pandharipande and Scheidegger of the Yau Zaslow conjecture, which equates the generating function for reduced Gromov-Witten invariants of a K3 surface with the generating function of partitions to...

I will describe the non-homological (i.e. enumerative) aspect of mirror symmetry for a particular toric Calabi-Yau 3-fold, the total space of the canonical bundle over $\mathbb P^2$. In this case, there is a simpler B-model on its mirror curve which...

I will attempt to explain Costello's set up of the problem of perturbative quantization of a gauge theory in the Batalin-Vilkovisky formalism, thus allowing us to formulate the main results of Costello and Li.

Continuing from February 14, I will attempt to explain Costello's set up of the problem of perturbative quantization of a gauge theory in the Batalin-Vilkovisky formalism, thus allowing us to formulate the main results of Costello and Li.

Continuing from February 28, I will attempt to explain Costello's set up of the problem of perturbative quantization of a gauge theory in the Batalin-Vilkovisky formalism, thus allowing us to formulate the main results of Costello and Li.

In his 2005 paper "The Gromov-Witten potential associated to a TCFT" Kevin Costello described a procedure for recovering an analogue of the Gromov-Witten potential directly out of a cyclic A-inifinity algebra or category. Applying his construction...

Givental's quantization formula describes higher genus invariants from genus zero data, the Frobenius manifold. I will describe this quantization and state Teleman's result that this quantization actually describes all semisimple cohomological field...
