Commuting quantities and exceptional W - algebras
Sets of commuting charges constructed from the current of a U(1) Kac-Moody algebra are found. There exists a set S n of such charges for each positive integer n > 1; the corresponding value of the central charge in the Feigin-Fuchs realization of the stress tensor is c = 13 − 6n − 6/n. The charges in each series can be written in terms of the generators of an exceptional W-algebra.

3 We consider commuting squares of nite dimensional von Neumann algebras having the algebra of complex numbers in the lower left corner. Examples include the vertex models, the spin models (in the sense of subfactor theory) and the commuting squares associated to nite dimensional Kac algebras. To any such commuting square we associate a compact Kac algebra and we compute the corresponding subfa...
متن کاملOn 1-dimensional Representations of Finite W -algebras Associated to Simple Lie Algebras of Exceptional Type
We consider the finite W -algebra U(g, e) associated to a nilpotent element e ∈ g in a simple complex Lie algebra g of exceptional type. Using presentations obtained through an algorithm based on the PBW-theorem, we verify a conjecture of Premet, that U(g, e) always has a 1-dimensional representation, when g is of type G2, F4, E6 or E7. Thanks to a theorem of Premet, this allows one to deduce t...

متن کاملCommuting Charges of the Quantum Korteweg-devries and Boussinesq Theories from the Reduction of W ∞ and W 1+∞ Algebras
Integrability of the quantum Boussinesq equation for c = −2 is demonstrated by giving a recursive algorithm for generating explicit expressions for the infinite number of commuting charges based on a reduction of the W∞ algebra. These charges exist for all spins s ≥ 2. Likewise, reductions of the W∞/2 and W(1+∞)/2 algebras yield the commuting quantum charges for the quantum KdV equation at c = ...
