W-Algebras of Negative Rank
K. Hornfeck
Recently it has been discovered that the W-algebras (orbifold of) WD_n can be defined even for negative integers n by an analytic continuation of their coupling constants. In this…
Coset Realization of Unifying W-Algebras
R. Blumenhagen, W. Eholzer, A. Honecker +2
We construct several quantum coset W-algebras, e.g. sl(2,R)/U(1) and sl(2,R)+sl(2,R) / sl(2,R), and argue that they are finitely nonfreely generated. Furthermore, we discuss in det…
Unifying W-Algebras
R. Blumenhagen, W. Eholzer, A. Honecker +2
We show that quantum Casimir W-algebras truncate at degenerate values of the central charge c to a smaller algebra if the rank is high enough: Choosing a suitable parametrization o…
Classification of Structure Constants for W-algebras from Highest Weights
K. Hornfeck
We show that the structure constants of W-algebras can be grouped according to the lowest (bosonic) spin(s) of the algebra. The structure constants in each group are described by a…
Explicit Construction of the BRST Charge for W_4
K. Hornfeck
We give the explicite form of the BRST charge Q for the algebra W_4=WA_3 in the basis where the spin-3 and the spin-4 field are primary as well as for a basis where the algebra clo…
W-algebras with set of primary fields of dimensions (3, 4, 5) and (3,4,5,6)
K. Hornfeck
We show that that the Jacobi-identities for a W-algebra with primary fields of dimensions 3, 4 and 5 allow two different solutions. The first solution can be identified with WA_4.…
