The Mori cone of certain Hassett spaces
 

I will discuss the Mori cones of several classes of Hassett spaces, i.e. moduli spaces of weighted pointed curves. I will explicitly describe some cases, including Hassett spaces whose universal family is a P¹ bundle, as well as other more complicated examples arising from certain blow-ups of projective space. Along the way, I will explain how these questions fit into the picture of the F-conjecture.
