Effective non-vanishing of global sections of multiple adjoint bundles for polarized 4-folds
Yoshiaki Fukuma
Let X be a smooth complex projective variety of dimension 4 and let L be an ample line bundle on X. In this paper, we study a natural number m such that h^{0}(m(K_{X}+L))>0 for any…

Effective non-vanishing of global sections of multiple adjoint bundles for polarized 3-folds
Yoshiaki Fukuma
Let be a smooth complex projective variety of dimension three and let be an ample line bundle on . In this paper, we provide a lower bound of the dimension of the global…
