Fields of fractions of quantum solvable algebras
Abstract
We introduce the notion of pure Q-solvable algebra. The quantum matrices, quantum Weyl algebra, Uq(n) are the examples. It is proved that the skew field of fractions of pure Q-solvable algebra is isomorphic to the skew field of twisted rational functions. This is the quantum version of Gelfand-Kirillov conjecture for solvable algebraic Lie algebras.
