Topics of the Summer School:


In its simplest form, the BernsteinGelfandGelfand
(BGG) correspondence associates a chain complex of
free graded modules over a polynomial algebra to a
module over an exterior algebra in way that generalizes
the classical Koszul complex. The resonance varieties
measure deviations from exactness of this chain complex
in a concrete, geometric fashion.

Polytopes (like cubes, pyramids, prisms)... have always been
studied since the beginning of mankind. They exist in nature
and are replicated by architects.

How to get to Catania:
A lot of companies fly directly to the Catania airport. The airport and the city center are well connected with public transportations.
Another option is the Palermo airport. There are buses leaving approximately every hour from the Palermo railway station to the Catania station.
Finally, Ryan Air flies to Trapani and to Comiso, but it takes quite a while to commute from there to Catania (TrapaniPalermo via bus is 90 minutes, then one has to change to the PalermoCatania bus.).
Palermo and Catania are also accessible via ferry from any big city in the mediterranean area and using public train transportations from Rome or Naples.
