Anti-ample bundle, nef vector bundle, big vector bundle
Indranil Biswas, Fatima Laytimi, D. S. Nagaraj +1
We prove that the direct image of an anti-ample vector bundle is anti-ample under any finite flat morphism of non-singular projective varieties. In the second part we prove some pr…

On the direct image of the adjoint line bundle
Indranil Biswas, Fatima Laytimi, D. S. Nagaraj +1
We give an algebraic-geometric proof of the fact that for a smooth fibration of projective varieties, the direct image of the adjoi…

Semiample and k-ample vector bundles
F. Laytimi, W. Nahm
We show that tensor products of semiample vector bundles are semiample. For k-ampleness in the sens of Sommese, we show that over compact complex manifolds tensor products of semia…
