Quantum and braided diffeomorphism groups

Quantum Algebra 2009-10-31 v1

Abstract

We develop a general theory of `quantum' diffeomorphism groups based on the universal comeasuring quantum group M(A)M(A) associated to an algebra AA and its various quotients. Explicit formulae are introduced for this construction, as well as dual quasitriangular and braided R-matrix versions. Among the examples, we construct the qq-diffeomorphisms of the quantum plane yx=qxyyx=qxy, and recover the quantum matrices Mq(2)M_q(2) as those respecting its braided group addition law.
