研究了紧致复流形上全纯向量丛的(k,s)-正性。(0,s)-正性就是Demailly s-正性,(k,1)-正线丛就是Sommese意义下的k-正线丛.这样我们就得到了半正向量丛的各种正性的统一理论。证明了(k,s)-正向量丛的几个新的消失定理,并将射影代数流形上的k-样本向量丛的消失定理推广到紧Kahler流形上的k-正向量丛。
We study the (k, s)-positivity for holomorphic vector bundles on compact complex manifolds. (0, s)-positivity is exactly the Demailly s-positivity and a (k, 1)-positive line bundle is just a k-positive line bundle in the sense of Sommese. In this way we get a unified theory for all kinds of positivities used for semipositive vector bundles. Several new vanishing theorems for (k, s)-positive vector bundles are proved and the vanishing theorems for k-ample vector bundles on projective algebraic manifolds are generalized to k-positive vector bundles on compact Kahler manifolds.
