Notes on Kodaira Energies of Polarized Varieties
§1. Conjectures Let V be a variety over C and let B = ∑ biBi be an effective Q-Weil divisor on V such that bi ≤ 1 for any i. Such a pair (V,B) will be called a log variety. It is said to be log terminal if it has only weak log terminal singularities in the sense of [KMM]. In this case, the Q-bundle KV + B is called the log canonical bundle of (V,B) and will be denoted by K(V,B). A Q-bundle L on...
متن کاملNotes from a problem session on support varieties
For groups other than p-groups, some work has been done for general situations [12, 13] and for simple groups [4, 5, 6]. Balmer [2] has made connections with the Picard group of the spectrum of the stable category. Nakano and the author have had some success extending the results to more general finite group schemes. For example, in the case of a p-restricted Lie algebra whose cohomology ring s...
متن کاملNotes on Toric Varieties from Mori Theoretic Viewpoint
The main purpose of this notes is to supplement the paper [Re], which treated Minimal Model Program (also called Mori’s Program) on toric varieties. We calculate lengths of negative extremal rays of toric varieties. As an application, we obtain a generalization of Fujita’s conjecture for singular toric varieties. We also prove that every toric variety has a small projective toric Q-factorializa...
متن کامل2 00 2 Notes on toric varieties Helena Verrill
These notes survey some basic results in toric varieties over a field F , with examples and applications. A computer algebra package (written by the author) is described which deals with both affine and projective toric varieties in any number of dimensions (written in both MAGMA [MAGMA] and GAP [GAP]). Among other things, the package implements the desingularization procedure, constructs some ...
متن کاملOospila bulava, a new emerald geometrid moth from South America (Lepidoptera, Geometridae, Geometrinae).
Warren (1897) described the genus Oospila for Phorodesma trilunaria Guenée, 1857 from Brazil. Prout (1912; 1932-1933) revised the genus, listing 48 species in the first publication and 58 species in the latter one, in Oospila. Cook and Scoble (1995) grouped eight related genera under Oospila, including 73 species and dividing these into 13 species groups. Pitkin (1996) relied on this revision w...
