Central extension of Virasoro type subalgebras of the Zamolodchikov--$w_{\infty}$ Lie algebra
, 2013 It is known that the centerless Zamolodchikov--$w_{\infty}$ $*$--Lie algebra of conformal field theory does not admit nontrivial central extensions, but the Witt $*$--Lie algebra, which is a sub--algebra of $w_{\infty}$, admits a nontrivial central ...

Two classes of Lie conformal superalgebras related to the Heisenberg–Virasoro Lie conformal algebra
Journal of Mathematical PhysicsIn this paper, we classify the Lie conformal superalgebras R=R0̄⊕R1̄, where R1̄ is of rank 1 and R0̄ is the Heisenberg–Virasoro Lie conformal algebra HV, which is a free C[∂]-module generated by L and H satisfying [LλL] = (∂ + 2λ)L, [LλH] = (∂ + λ)H, [HλH] = 0. Based on this, we construct two classes of Lie conformal superalgebras denoted by HVS(α) and

, 2008 . We demonstrate that the Kac-Moody and Virasoro-like algebras on Riemann surfaces of arbitrary genus with two punctures introduced by Krichever and Novikov are in two ways linearly related to Kac-Moody and Virasoro algebras on S 1.

Sugawara and vertex operator constructions for deformed Virasoro algebras
, 2006 23 pagesInternational audienceFrom the defining exchange relations of the A_{q,p}(gl_{N}) elliptic quantum algebra, we construct subalgebras which can be characterized as q-deformed W_N algebras.

AN INFINITE CLASS OF NEW CONFORMAL FIELD-THEORIES WITH EXTENDED ALGEBRAS
, 1988 A large class of 2D conformal field theories with extended Virasoro algebras related to the GKO construction on the coset SU(2)⊗SU(2)/SU(2) is introduced. Through a Feigin-Fuchs construction the Kac formula is deduced.

ħ-vertex algebras and chiralization of star products [PDF]
We develop the theory of ħ-vertex algebras, algebraic structures closely related to vertex algebras but with a deformed translation covariance axiom.
