Meng Chen, The Noether inequality for algebraic threefolds

B236-1 IBS, Korea, Republic of

    Speaker Meng Chen Fudan University In this talk, I will present a complete proof for the following theorem: the inequality K3 ≥ 4/3 pg-10/3 holds for all 3-folds of general type.

Gian Pietro Pirola, Asymptotic directions on the moduli space of curves

B236-1 IBS, Korea, Republic of

    Speaker Gian Pietro Pirola University of Pavia We present some computational improvements that allow us to study asymptotic lines in the tangent of the moduli space Mg of the curves of genus g. The asymptotic directions are those tangent directions that are annihilated by the second fundamental form induced by the Torelli map.

Benjamin McMillan, Secondary Characteristic classes and Chern-Weil theory of (Haefliger) singular foliations I

B236-1 IBS, Korea, Republic of

    Speaker Benjamin McMillan IBS CCG Foliations have a theory of characteristic classes that is much like that of vector bundles, but with notable differences. Some of the characteristic classes of a foliation come from its induced normal bundle, but there are additional secondary classes that depend on more detailed information about the foliation.

Gian Pietro Pirola, Sections of the Jacobian bundles of plane curves and applications

B236-1 IBS, Korea, Republic of

    Speaker Gian Pietro Pirola University of Pavia We study normal functions (sections of the Jacobian bundle) defined on the moduli space of pointed plane curves. Using the infinitesimal Griffiths invariant (refined by M. Green and C. Voisin) we show that a normal function with nontrivial but sufficiently "small" support cannot be "locally constant".

Han-Bom Moon, Ulrich bundles on intersections of quadrics

B236-1 IBS, Korea, Republic of

    Speaker Han-Bom Moon Fordham University An Ulrich bundle is a vector bundle with very strong cohomology vanishing conditions. Eisenbud and Schreyer conjectured that every smooth projective variety possesses an Ulrich bundle. Despite many results on low dimensional varieties and special varieties, the general existence is unknown. In this talk, I will describe recent
