On Kodaira energy and adjoint reduction of polarized threefolds
Takao Fujita
Here we study and classify polarized threefolds whose Kodaira energies are less than -1/2. The Kodaira energy of a polarized manifold (M, L), a pair consisting of a smooth complex…
A note on scrolls of smallest embedded codimension
Takao Fujita
Let be a submanifold of of dimension . Suppose that $(M,{\Cal O}_M(1))\cong{\Bbb P}({\Cal E}),{\Cal O}(1))$ for some vector bundle ${\Cal E}$ on a surface …
Towards a separation theorem of points by adjoint linear systems on polarized threefolds
Takao Fujita
Main Result: Let be a smooth complex polarized threefold. Then the linear system separates any two different points on for any , where is the cano…
Remarks on Ein-Lazarsfeld criterion of spannedness of adjoint bundles of polarized threefolds
Takao Fujita
Let B be a nef and big line bundle on a smooth complex threefold X with canonical bundle K. Let x be a point on X and suppose that BC\ge3 for any curve C passing x, B^2S\ge7 for an…
Kodaira energies of polarized log varieties
T. Fujita
Let L be an ample line bundle on a log variety (V, D) having only log terminal singularities.The Kodaira energy of such a triple (V, D, L) is defined as follows: κε=-Inf{t\in Q | K…
Notes on Kodaira energies of polarized varieties
Takao Fujita
The Kodaira energy of a polarized manifold (M,L) is defined by κε(M,L)=-Inf{t\in Q|κ(K+tL)\ge 0}. Here we propose a couple of conjectures and announce several partial results. 3-di…
