Abstract : 

    We give an analytic version of the injectivity theorem by using multiplier ideal sheaves, and prove some extension theorems for the log canonical bundle of dlt pairs. Moreover, by combining techniques of the minimal model program, we obtain results for semi-ampleness related to the abundance conjecture in birational geometry and the semi-ampleness conjecture for hyperKaehler manifolds. This is a joint work with Shin-ichi Matsumura.
