Hirotachi Abo, On the discriminant locus of a vector bundle
The discriminant locus of a vector bundle is the set of “singular” global sections of the vector bundle. In general, the discriminant locus of a vector bundle is a hypersurface of the projective space of global sections of the vector bundle. This talk is concerned with the problem of classifying vector bundles whose discriminant locus is not a hypersurface. This is joint work with R. Lazarsfeld and G. Smith.
Liena Colarte-Gómez, aCM projections of Veronese varieties and invariants of finite abelian groups.
In this talk we consider linear projection of Veronese varieties parameterized by invariants of degree d of a finite abelian subgroup of GL(n+1) of order d. We will see that they are arithmetically Cohen-Macaulay (aCM) varieties and what we can say so far about their minimal free resolutions.
