Abstract:
For a pseudo-effective pair (X, B) which is the limit of non-pseudo-effective pairs (X, B_i), Gongyu consturct a (K_X+B)-trivial fibration and reduce the nonvanishing conjecture for this pair to that for pairs of lower dimension. In this talk, I will introduce his construction in detail and discuss some of its applications, for example, the rationality of pseudo-effective threshold and the nonvanishing conjecture for rationally connected pairs and uniruled pairs.
