We introduce the notion of pure Q-solvable algebra. The quantum matrices, Ε½ . quantum Weyl algebra, U n are the examples. It is proved that the skew field of q fractions of a pure Q-solvable algebra R is isomorphic to the skew field of twisted rational functions. This is a quantum version of the Gel

β¦ Synopsis
Let L be an arbitrary Lie algebra. Then by Cohn's Theorem its universal Ε½ . enveloping algebra can be embedded in a skew field D L . We study this skew Ε½ . field in the case when L is a free Lie algebra and prove that in this case D L is Ε½ . isomorphic to the universal field of fractions for the free associative algebra U L . We apply this theorem to obtain new results on free fields.

We write det L L / 0 q y y if the matrix formed by brackets between elements of a basis of L L is nonsinguy lar. Unlike Lie super algebras, a Lie color algebra L L may have det L L / 0 and a Ε½ . universal enveloping algebra U L L which is not prime. We will provide examples Ε½ . and show that U L L i
We consider the continued fraction expansion of certain algebraic formal power series when the base field is finite. We are concerned with the property of the sequence of partial quotients being bounded or unbounded. We formalize the approach introduced by Baum and Sweet (1976), which applies to the
