タイトル	A TRANSCENDENTAL APPROACH TO KOLLÁR’S INJECTIVITY THEOREM
著者	Fujino, Osamu Fujino, Osamu
抄録	We treat Kollár's injectivity theorem from the analytic (or differential geometric) viewpoint. More precisely, we give a curvature condition which implies Kollár type cohomology injectivity theorems. Our main theorem is formulated for a compact Kähler manifold, but the proof uses the space of harmonic forms on a Zariski open set with a suitable complete Kähler metric. We need neither covering tricks, desingularizations, nor Leray's spectral sequence.
