Half Twists of Hodge Structures of Cm-type
نویسنده
چکیده
To a Hodge structure V of weight k with CM by a field K we associate Hodge structures V −n/2 of weight k + n for n positive and, under certain circumstances, also for n negative. We show that these ‘half twists’ come up naturally in the Kuga-Satake varieties of weight two Hodge structures with CM by an imaginary quadratic field.

Half Twists and the Cohomology of Hypersurfaces
A Hodge structure V of weight k on which a CM eld acts de nes, under certain conditions, a Hodge structure of weight k 1, its half twist. In this paper we consider hypersurfaces in projective space with a cyclic automorphism which de nes an action of a cyclotomic eld on a Hodge substructure in the cohomology. We determine when the half twist exists and relate it to the geometry and moduli of th...
متن کاملHodge Structures of Cm-type
We show that any effective Hodge structure of CMtype occurs (without having to take a Tate twist) in the cohomology of some CM abelian variety over C. As a consequence we get a simple proof of the theorem (due to Hazama) that the usual Hodge conjecture for the class of all CM abelian varieties implies the general Hodge conjecture for the same class.
متن کاملReal multiplication on K3 surfaces and Kuga Satake varieties
The endomorphism algebra of a K3 type Hodge structure is a totally real field or a CM field. In this paper we give a low brow introduction to the case of a totally real field. We give existence results for the Hodge structures, for their polarizations and for certain K3 surfaces. We consider the Kuga Satake variety of these Hodge structures and we discuss some examples. Finally we indicate vari...
متن کاملOn the Maximal Unramified Quotients of p-Adic Étale Cohomology Groups and Logarithmic Hodge–Witt Sheaves Dedicated to Professor K. Kato on his 50th birthday
Let OK be a complete discrete valuation ring of mixed characteristic (0, p) with perfect residue field. From the semi-stable conjecture (Cst) and the theory of slopes, we obtain isomorphisms between the maximal unramified quotients of certain Tate twists of p-adic étale cohomology groups and the cohomology groups of logarithmic Hodge-Witt sheaves for a proper semi-stable scheme over OK . The ob...
متن کاملIntroducing New Structures for D-Type Latch and Flip-Flop in Quantum-Dot Cellular Automata Technology and its Use in Phase-Frequency Detector, Frequency Divider and Counter Circuits
Quantum-dot cellular automata (QCA) technology is an alternative to overcoming the constraints of CMOS technology. In this paper, a new structure for D-type latch is presented in QCA technology with set and reset terminals. The proposed structure, despite having the set and reset terminals, has only 35 quantum cells, a delay equal to half a cycle of clocks and an occupied area of 39204 nm2. T...
