In this paper we study relations between different (q,h)-Weyl algebras. We also show an embedding of the q -deformed universal enveloping algebra 3a1ff7fadb96854e40cc" title="Click to view the MathML source">Uq=Uq(sl(2)) into a tensor product of two (q,h)-Weyl algebras when q≠1. This allows us to study the limiting case q→1 in the so-called structure ladder of Uq.
