Title：The intersection theory of transcendental b-divisors I
Abstract：I will explain the notion of b-divisors over a compact Kähler manifold.
In the first talk, 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, as conjectured by Dang—Favre.

Title：The intersection theory of transcendental b-divisors II
Abstract：In the second talk, we will explore consequences of this intersection theory and show how it leads to a number of new inequalities in pluripotential theory.
