摘要

．设(X, L)表示五维的极化流形。本研究考虑m≥6的K X + mL整体切片的维数。特别地，我们证明了h 0 (K X + mL)≥(cid:0) m−15 (cid:1)对于任何具有h 0 (L) >的极化5倍(X, L)。此外，我们还考虑(X, L)与h 0 (K X + mL) = (cid:0) m−15 (cid:1)对于某些m≥6与h 0 (L) > 0。

ON THE DIMENSION OF THE GLOBAL SECTIONS OF THE ADJOINT BUNDLE FOR POLARIZED 5-FOLDS

. Let ( X , L ) denote a polarized manifold of dimension ﬁve. This study considers the dimension of the global sections of K X + mL with m ≥ 6. In particular, we prove that h 0 ( K X + mL ) ≥ (cid:0) m − 1 5 (cid:1) for any polarized 5-fold ( X , L ) with h 0 ( L ) > 0. Furthermore, we also consider ( X , L ) with h 0 ( K X + mL ) = (cid:0) m − 1 5 (cid:1) for some m ≥ 6 with h 0 ( L ) > 0.

期刊介绍： The Kyushu Journal of Mathematics is an academic journal in mathematics, published by the Faculty of Mathematics at Kyushu University since 1941. It publishes selected research papers in pure and applied mathematics. One volume, published each year, consists of two issues, approximately 20 articles and 400 pages in total. More than 500 copies of the journal are distributed through exchange contracts between mathematical journals, and available at many universities, institutes and libraries around the world. The on-line version of the journal is published at "Jstage" (an aggregator for e-journals), where all the articles published by the journal since 1995 are accessible freely through the Internet.
