Virasoro algebra from harmonic superspace

Physical Review D, 1992
Using harmonic superspace techniques we construct a new field realization of the Virasoro algebra. The main conformal objects are U(1) Cartan tensors instead of the U(1) Lorentz ones. The new conformal model, which admits moreover a {ital d}=2 (4,0) global supersymmetry, is constructed out of the infinitely relaxed Howe-Stelle-Townsend and Fayet ...

GENERALIZED DEFORMED VIRASORO ALGEBRAS

Modern Physics Letters A, 1992
The deformed Virasoro algebra is a structure, generated by a generalized deformed oscillator algebra. The usual or the q-deformed centerless Virasoro algebras are special cases of this structure, and their properties can be reduced from the properties of the generalized deformed algebra.

Aperiodic Virasoro algebra

Journal of Mathematical Physics, 2000
An aperiodic analog to the Virasoro algebra is introduced and its representation theory is investigated. In particular, highest and lowest weight representations are constructed. An analog to the Kac determinant formula is derived and the implications for unitarity are discussed.

Generalized Heisenberg-Virasoro algebras

Frontiers of Mathematics in China, 2009
The authors introduce the generalized Heisenberg-Virasoro algebra, which is a generalization of the twisted Heisenberg-Virasoro Lie algebra \(H_{\text{Vir}}\) from the integer ring \(\mathbb Z\) to an additive subgroup \(M\) of a field \(\mathbb F\). For the exact definition see Section 2 (Definition 1) of the paper.

Virasoro algebra and Teichm�ller spaces

Functional Analysis and Its Applications, 1987
It is shown that the set of equivalence classes of triples \((C,p,t)\), where \(C\) is a complex Riemann surface of genus \(g\), \(p\) a point of \(C\) and \(t\) an \(\infty\)-jet of a coordinate at \(p\) is infinitesimally a double coset space of the central extension of the group of diffeomorphisms of the circle (the Virasoro group) modulo analogues ...

The Virasoro Algebra

1989
In this chapter we shall study the Lie algebra Vect S1 of vector fields on a circle and some of its generalizations. The Lie algebra Vect S1 has a central extension, the Virasoro algebra. The representation theory of the Virasoro algebra is closely related to the representation theory of affine Lie algebras.

Höchstgewichtsdarstellungen der Virasoro-Algebra

1994
Die Untersuchung unendlichdimensionaler Lie-Algebren begann in den sechziger Jahren. Die in der Physik bekanntesten Beispiele unendlichdimensionaler Lie-Algebren sind die Strom-Algebren und die Virasoro-Algebra. Die Strom-Algebren werden auch Kac-Moody-Algebren genannt.
