"Local systems on the punctured disc"

Abstract: We consider local systems of F-modules on the etale site of the 
p-adic punctured disc, where F is the algebraic closure of a finite field
of  characteristic different from p. We explain how such local systems admit a 
canonical decomposition which is fully analogous to the "break decomposition" 
for l-adic representations of a complete DVR of characteristic p.

"Integrable regimes in nonlocal nonlinear optics"

Abstract: Nonlocal nonlinear optics (NNO) is one of the most important 
developments in modern optics. In the recent years it was shown that 
nonlocality plays a crucial role in the propagation of stable spatial 
"solitons" in three dimensions. The problem of the integrability of these kind 
of systems is still open, and, apart few (very interesting) cases the main 
theoretical results on the behaviour of solutions are obtained numerically. 
Most of the models in NNO are based on a nonlocal nonlinear Schrodinger (NNLS) 
type equation. The dispersionless limit of the NNLS equation is equivalent to 
the geometric optics limit. We analyze in detail singular phase solutions and 
introduce a class of integrable nonlocal perturbations. We also discuss the 
possibility to introduce wave(dispersive)-deformations for different nonlocal 
models.

Prof. Marco Manetti (La Sapienza, Roma)

"Periods of generalized deformations"

Abstract: A generalized deformation of a complex manifold is defined 
algebraically as a solution, up to gauge, of the Maurer-Cartan equation in the 
algebra of polyvector fields. We show that in the Kaehler case, every 
generalized deformation gives canonically holomorphic maps into the 
Grassmannian of graded subspaces of the De Rham cohomology. For classical 
deformations the above maps reduces to Griffiths period maps.
