Description
This is a joint work with A. Buch, P.-E. Chaput and L. Mihalcea. In this talk I shall explain that rational connectedness results as well as a good control on the singularities of some subvarieties of the variety of rational curves lying on a grassmannian (and some other rational homogeneous spaces) imply positivity results in quantum K-theory.
