Title
Positive cones of cycles and Seshadri constants on certain projective varieties.
Abstract: In the first part of the talk I will talk about nef cones of divisors and pseudo-effective cones of k-cycles on products of projective bundles over curves. In the 2nd part, I will present some results about the Seshadri constants of ample line bundles on various blow-ups of projective spaces.
