Abstract: | It is well known that the blow-up of the projective plane has a Cremona symmetry of the Weyl group of the root system of type E. This was generalized to a T-shaped Cremona symmetry of higher dimensional multi-projective spaces by Coble and Mukai. Using this framework I will describe the “Jacobians” of del Pezzo surfaces dP_d, and construct several extremal elliptic fibrations over the d-dimensional projective space. |
