KASS-seminarium

Abstrakt finns enbart på engelska: I will explain the notion of b-divisors over a compact Kähler manifold. We will show that nef b-divisors, being a cohomological notion, are in bijection with a class of currents. The analytic theory can therefore be applied while studying nef b-divisors. As a consequence, we establish the intersection theory of nef b-divisors, answering a question of Dang-Favre.
