General informations on the School and Workshop.
The School and the Workshop will take place at

The aim of the Workshop is to discuss the state of art. Interested people are kindly requested to submit the title and an abstract of their Communication within September 9^th to

The School is mainly aimed to Phd students and young researchers in Algebraic Geometry, introducing the participants to research, beginning from a basic level with a view towards the applications and to the most recent results.
The Cremona group of the birational transformations of a projective n-dimensional space is, still now, not very much understood, at least if n is not lesser than 3. The School will focus on the description of the finite subgroups of the Cremona group of projective plane and on the classical series of examples of Cremona transformations of projective 3-dimensional space. The relations with the modern birational geometry will be discussed as well various related topics, among them: homaloidal hypersurfaces, special linear systems of plane curves, congruences of rational curves and their birational classification, rationality problems for conic bundles, etcetera.

Schedule.
The School will start on Monday, 19^th at 13.00 and it will end on Saturday, 24^th at 12.00. Workshop will start on Thursday 22^nd at 14.00 and it will end on Friday 23^rd at 12.00. On Thursday evening a social dinner open to the participants of the School/Workshop will be organized.

Registration and Registration Fee.
All the participants must fill in the on line registration form within September, 9^th and pay a registration fee of 70 euros cash at Registration. For other methods of payment please contact the organizers.

Financial supports for Participants.
