N = 2 W-supergravity
We quantise the classical gauge theory of N = 2 w ∞-supergravity and show how the underlying N = 2 super-w ∞ algebra gets deformed into an N = 2 super-W ∞ algebra. Both algebras contain the N = 2 super-Virasoro algebra as a subalgebra. We discuss how one can extract from these results information about quantum N = 2 W N-supergravity theories containing a finite number of higher-spin symmetries ...
متن کاملN=2 Supersymmetric W-algebras
We investigate extensions of the N=2 super Virasoro algebra by one additional super primary field and its charge conjugate. Using a supersymmetric covariant formalism we construct all N=2 super W-algebras up to spin 5/2 of the additional generator. Led by these first examples we close with some conjectures on the classification of N=2 SW(1, ∆) algebras.
متن کاملW-strings from N = 2 Hamiltonian Reduction and Classification of N = 2 Super W-algebras
We present an algebraic approach to string theory, using a Hamiltonian reduction of N = 2 WZW models. An embedding of sl(1|2) in a Lie superalgebra determines a niltopent subalgebra. Chirally gauging this subalgebra in the corresponding WZW action leads to an extension of the N = 2 superconformal algebra. We classify all the embeddings of sl(1|2) into Lie superalgebras: this provides an exhaust...
متن کاملStudy of the R-(Zr,W)-(O,N) (R = Y, Nd, Sm, Gd, Yb) oxynitride system
The replacement of tantalum by the couple Zr/W within the RTa-O-N systems (R = Y, Nd, Sm, Gd, Yb), enables the preparation of novel oxide and oxynitride phases in the R-Zr-W-O-N system. R2Zr2-xWxO7+x oxides exhibit the fluorite-type (x<0.9) and scheelite (x 1) structures. Corresponding oxynitride compositions are of the fluorite type and show different colors, for example in the case of ytter...
متن کاملLow Complexity Converter for the Moduli Set {2^n+1,2^n-1,2^n} in Two-Part Residue Number System
Residue Number System is a kind of numerical systems that uses the remainder of division in several different moduli. Conversion of a number to smaller ones and carrying out parallel calculations on these numbers will increase the speed of the arithmetic operations in this system. However, the main factor that affects performance of system is hardware complexity of reverse converter. Reverse co...
