Prof. Alexander Zabrodsky

**Prof.
Boris Dubrovin** (SISSA)

The lectures will be held at the Edmond Safra Campus Givat Ram, Jerusalem

First talk:
Thursday, April 30th, Colloquium, 14:30-15:30
Einstein Institute of Mathematics, Lecture Hall 2
Title:
A gathering in memory of Abstract:
The study of interconnections between integrable systems and topology
of Deligne - Mumford moduli spaces of stable algebraic curves and their
generalisations has been initiated by E.Witten and M.Kontsevich at the
beginning of 90s. In the talk I will explain some basic ideas about the
conjectural correspondence between the class of smooth projective varieties
with semisimple quantum cohomology and a class of hierarchies of integrable
PDEs. |

Second talk:
Sunday, May 3rd, 16:00-17:00, Ross 70A
Title: Abstract:
I will construct a complete set of eigenvectors of commuting
Hamiltonian operators arising in the theory of quantum Hopf equation.
Such operators naturally arise in the setting of
Symplectic Field Theory (SFT)
by Y.Eliashberg, A.Givental and H.Hofer in computations of the SFT invariants
of a disk. |

Third talk:
Tuesday, May 5th, 14:00-15:00 Ross 70A
Title: Abstract:
It will be computed the generating function of degree zero Gromov -
Witten invariants and their descendants of a smooth projective threefold.
For the Calabi - Yau case connections of the resulting formula with the
MacMahon generating function in the theory of plane partitions will be
discussed. |
