An involution and dynamics for the $q$-deformed quantum top | | A.Yu.Alekseev

29 Jun 1994 | | Abstract: | It is known that the involution corresponding to the compact form is incompatible with comultiplication for quantum groups at $ q =1$. In this paper we consider the quantum algebra of functions on the deformed space $T^{*}G_{q}$ which includes both the quantum group and the quantum universal enveloping algebra as subalgebras. For this extended object we construct an anti-involution which reduces to the compact form $*$-operation in the limit $q
ightarrow 1$. The algebra of functions on $T^{*}G_{q}$ endowed with the $*$-operation may be viewed as an algebra of observables of a quantum mechanical system. The most natural interpretation for such a system is a deformation of the quantum symmetric top. We suggest a discrete dynamics for this system which imitates the free motion of the top. | | Source: | arXiv, hep-th/9406196 | | Services: | Forum | Review | PDF | Favorites | |
