4:00 pm Tuesday, October 16, 2012 Algebraic Geometry Seminar: On the speciality of linear systems in P^nby Olivia Dumitrescu (UC Davis) in HB 227- Given a linear system in the projective space with assigned multiple general points we compute the cohomology groups of its strict transforms via the blow-up of its linear base locus. In particular, this computes the dimension of all cohomology groups for effective divisors in $\bar M_{0,n}$ interpolating points. We investigate the speciality of linear systems with linear base locus. This is joint work with C. Brambilla and E. Postinghel
