Chiral Ring in the 4 D W 3 String
نویسنده
چکیده
I summarize some recent results obtained in collaboration with P. Bouwknegt and K. Pilch on the spectrum of physical states in W 3 gravity coupled to c = 2 matter. In particular, it is shown that the algebra of operators corresponding to physical states – defined as a semi-infinite (or BRST) cohomology of the W 3 algebra – carries the structure of a G-algebra. This G-algebra has a quotient which is isomorphic to the G-algebra of polyvector fields on the base affine space of SL(3, I C). Details will appear elsewhere.

Effects of Disc Insulator Type and Corona Ring on Electric Field and Voltage Distribution over 230-kV Insulator String by Numerical Method
Insulator strings with several material and profiles are very common in overhead transmission lines. However, the electric field and voltage distribution of insulator string is uneven which may easily lead to corona, insulators’ surface deterioration and even flashover. So the calculation of the electric field and voltage distribution along them is a very important factor in the operation time....
متن کاملThe chiral ring of AdS3/CFT2 and the attractor mechanism
We study the moduli dependence of the chiral ring in N = (4, 4) superconformal field theories, with special emphasis on those CFT's that are dual to type IIB string theory on AdS 3 ×S 3 ×X 4. The chiral primary operators are sections of vector bundles, whose connection describes the operator mixing under motion on the moduli space. This connection can be exactly computed using the constraints f...
متن کاملExact chiral ring of AdS3/CFT2
We carry out an exact worldsheet computation of tree level three-point correlators of chiral operators in type IIB string theory on AdS3×S×T 4 with NS-NS flux. We present a simple representation for the string chiral operators in the coordinate basis of the dual boundary CFT. Striking cancelations occur between the three-point functions of the H3 and the SU(2) WZW models which result in a simpl...
متن کاملN = 1 Special Geometry , Mixed Hodge Variations and Toric Geometry
We study the superpotential of a certain class of N = 1 supersymmetric type II compactifications with fluxes and D-branes. We show that it has an important two-dimensional meaning in terms of a chiral ring of the topologically twisted theory on the world-sheet. In the open-closed string B-model, this chiral ring is isomorphic to a certain relative cohomology group V , which is the appropriate m...
متن کاملThe $w$-FF property in trivial extensions
Let $D$ be an integral domain with quotient field $K$, $E$ be a $K$-vector space, $R = D propto E$ be the trivial extension of $D$ by $E$, and $w$ be the so-called $w$-operation. In this paper, we show that $R$ is a $w$-FF ring if and only if $D$ is a $w$-FF domain; and in this case, each $w$-flat $w$-ideal of $R$ is $w$-invertible.
