        "description":"In 1964, Horrocks proved that a vector bundle on a projective space splits as a sum of line bundles if and only if it has no intermediate cohomology. Generalizations of this criterion, under additional hypotheses, have been proven for other toric varieties, for instance by Eisenbud-Erman-Schreyer for products of projective spaces, by Schreyer for Segre-Veronese varieties, and Ottaviani for Grassmannians and quadrics. This talk is about a splitting criterion for arbitrary smooth projective toric varieties, as well as an algorithm for finding indecomposable summands of sheaves and modules in the more general setting of Mori dream spaces.",

To estimate the causal impacts of the policy, we conduct surveys in communities around the discontinuity in the state government\u2019s policy assignment rule. We find that the marginal constituency assigned to the reservation policy experiences a drop in cross-caste network links and an increase in homophily. Consistent with increased homophily, reservation leads to less social learning when information is introduced to the community. While reservation is active, we find no change in the salience of caste concerns and no shifts in beliefs about trustworthiness, competence, or work ethic, among others, across caste. Finally, consistent with prior work, reservation improves access to redistribution schemes. Both lower and upper castes benefit, indicating no crowd-out at the expense of upper castes.\r\n\r\nThis talk is presented by the Economic Development Seminar, sponsored in part by the Department of Economics through a generous gift given by Jay and Beth Rakow.
