Abstract

For a certain class of Lie bialgebras (A,A^*) the corresponding quantum universal enveloping algebras U_q(A) are prooved to be equivalent to quantum groups Fun_q(F^*), F^* being the factor group for the dual group G^*. This property can be used to simplify the process of quantization. The described class appears to be wide enough to contain all the standard quantizations of infinite series. The properties of the groups F^* are explicitly demonstrated for the standard deformations U_q(SL(n)). It is shown that for different A^* (remaining in the described class of Lie bialgebras) the same algorithm leads to the nonstandard quantizations.
