Convex PBW-type Lyndon Bases and Restricted Two-parameter Quantum Group of Type F4
نویسندگان
چکیده
The convex PBW-type Lyndon basis for two-parameter quantum group Ur,s (F4)is given. Assume that rs−1 is a primitive ℓ-th root of unity with ℓ odd, then the restricted $${\mathfrak{u}_{r,s}}({F_4})$$ as quotient Ur,s(F4) pointed, and Drinfel’d double structure under certain condition. All Hopf isomorphisms are determined, necessary sufficient condition to be ribbon algebra singled out by describing left right integrals.

Convex Bases of Pbw Type for Quantum Affine Algebras
This note has two purposes. First we establish that the map defined in [L, §40.2.5 (a)] is an isomorphism for certain admissible sequences. Second we show the map gives rise to a convex basis of Poincaré–Birkhoff–Witt (PBW) type for U, an affine untwisted quantized enveloping algebra of Drinfeld and Jimbo. The computations in this paper are made possible by extending the usual braid group actio...

QUANTUM LIE ALGEBRAS OF TYPE An POSITIVE, PBW BASES AND THE YANG-BAXTER EQUATION
We show explicitly a generalised Lie algebra embedded in the positive and negative parts of the Drinfeld-Jimbo quantum groups of type An. Such a generalised Lie algebra satisfy axioms closely related to the ones found by S.L. Woronowicz. For the universal enveloping algebra of such generalised Lie algebras we establish several conditions in order to obtain bases of type Poincaré-Birkhoff-Witt. ...
متن کاملOn isomorphism of two bases in Morrey-Lebesgue type spaces
Double system of exponents with complex-valued coefficients is considered. Under some conditions on the coefficients, we prove that if this system forms a basis for the Morrey-Lebesgue type space on $left[-pi , pi right]$, then it is isomorphic to the classical system of exponents in this space.
متن کاملA SINGLE SERVER BERNOULLI VACATION QUEUE WITH TWO TYPE OF SERVICES AND WITH RESTRICTED ADMISSIBILITY
A single server queue with Bernoulli vacation has been considered. In addition the admission to queue is based on a Bernoulli process and the server gives two type of services. For this model the probability generating function for the number of customers in the queue at different server's state are obtained using supplementary variable technique. Some performance measures are calculated. Some ...
