• Luca Schaffler, An Explicit Wall Crossing for the Moduli Space of Hyperplane Arrangements

    B236-1 IBS, Korea, Republic of
    Algebraic Geometry Seminar

        Speaker Luca Schaffler Roma Tre University The moduli space of hyperplanes in projective space has a family of geometric and modular compactifications that parametrize stable hyperplane arrangements with respect to a weight vector. Among these, there is a toric compactification that generalizes the Losev-Manin moduli space of points on the line. We study

    B236-1 IBS, Korea, Republic of
    Algebraic Geometry Seminar

        Speaker Luca Schaffler Roma Tre University Smooth minimal surfaces of general type with K2=1, pg=2, and q=0 constitute a fundamental example in the geography of algebraic surfaces, and the 28-dimensional moduli space M of their canonical models admits a modular compactification M via the minimal model program. We describe eight new irreducible boundary
