Hyperplane Arrangements, II


This is the 2nd talk of two on hyperplane arrangements. The talk will be centered on a resolution of singularities for subspace arrangements. I will introduce Fulton-Macpherson spaces, the "wonderful models" of De Concini--Procesi, and some variations on these themes. Specializing to the case of hyperplane arrangements, we actually get log resolutions, which allow us to compute multiplier ideals, recovering a recent result of Mustata.
