This course is an introduction to complex analytic techniques in
algebraic geometry. Topics that will likely be covered include:
(1) Plurisubharmonic functions and closed positive currents, Lelong numbers;
(2) H¨ormander’s L2 estimates for @;
(3) Ohsawa-Takegoshi extension theorem (as a consequence of H¨ormander);
(4) Demailly’s regularization theorem for currents;
(5) Multiplier ideal sheaves and Nadel vanishing theorem;
(6) Applications to algebraic geometry;
(7) Invariance of plurigenera;
(8) Fujita’s approximation theorem;
(9) Boucksom-Demailly-Paun-Peternell’s characterization of uniruled manifolds;
(10) Openness conjecture and strong openness conjecture.
