The Lie algebra D̂, which is the unique non-trivial central extension of the Lie algebra D of differential operators on the circle [KP1], has appeared recently in various models of two-dimensional quantum field theory and integrable systems, cf., e.g., [BK, FKN, PRS, IKS, CTZ, ASvM]. A systematic study of representation theory of the Lie algebra D̂, which is often referred to as W1+∞ algebra, was initiated in [KR]. In that paper irreducible quasi-finite highest weight representations of D̂ were… 
Invariant theory and the W 1 + ∞ algebra with negative integral central charge
The vertex algebraW1+∞,c with central charge c may be defined as a module over the universal central extension of the Lie algebra of differential operators on the circle. For an integer n ≥ 1, it was
Representation theory of the vertex algebraW1+∞
In our paper [KR] we began a systematic study of representations of the universal central extension of the Lie algebra of differential operators on the circle. This study was continued in the paper

Central extensions of some Lie algebras

Symplectic Fermions - Symmetries of a Vertex Operator Algebra
The model of d symplectic fermions constructed by Abe [1] gives an example of a C2cofinite vertex operator algebra admitting logarithmic modules. While the case d = 1 is a rigorous formulation of the
