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…
A numerical characterization of polarized manifolds (X,L) with K_{X}=-(n-i)L by the ith sectional geometric genus and the ith Δ-genus
Yoshiaki Fukuma
Let (X,L) be a polarized manifold of dimension n. In this paper, by using the ith sectional geometric genus and the ith Δ-genus, we will give a numerical characterization of (X,L)…
Remarks on the second sectional geometric genus of quasi-polarized manifolds and their applications
Yoshiaki Fukuma
In our previous papers, we investigated a lower bound for the second sectional geometric genus of -dimensional polarized manifolds and by using these, we st…
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…
A lower bound for of quasi-polarized surfaces with non-negative Kodaira dimension
Yoshiaki Fukuma
Let be a smooth projective surface over the complex number field and let be a nef-big divisor on . Here we consider the following conjecture; If the Kodaira dimension $κ…
