Intersection Numbers of Extremal Rays on Holomorphic Symplectic Varieties
Suppose X is a smooth projective complex variety. Let N1(X,Z) ⊂ H2(X,Z) and N (X,Z) ⊂ H(X,Z) denote the group of curve classes modulo homological equivalence and the Néron-Severi group respectively. The monoids of effective classes in each group generate cones NE1(X) ⊂ N1(X,R) and NE (X) ⊂ N(X,R) with closures NE1(X) and NE 1 (X), the pseudoeffective cones. These play a central rôle in the bira...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

متن کاملZero-cycles on varieties over finite fields
For any field k, Milnor [Mi] defined a sequence of groups K 0 (k), K M 1 (k), K M 2 (k), . . . which later came to be known as Milnor K-groups. These were studied extensively by Bass and Tate [BT], Suslin [Su], Kato [Ka1], [Ka2] and others. In [Som], Somekawa investigates a generalization of this definition proposed by Kato: given semi-abelian varieties G1, . . . , Gs over a field k, there is a...
متن کاملExtremal Rays and Automorphisms of Holomorphic Symplectic Varieties
For last fifteen years, numerous authors have studied the birational geometry of projective irreducible holomorphic symplectic varieties X, seeking to relate extremal contractions X → X ′ to properties of the Hodge structures on H(X,Z) and H2(X,Z), regarded as lattices under the Beauville-Bogomolov form. Significant contributions have been made by Huybrechts, Markman, O’Grady, Verbitsky, and ma...
