Abstract
Let (resp.
) be the
-part (resp.
-part) of the Drinfeld-Jimbo quantum group of type AN over a field K. With respect to Jimbo relations and the PBW K-basis
of
(resp.
) established by Yamane, it is shown, by constructing an appropriate monomial ordering
on
, that
(resp.
) is a solvable polynomial algebra. Consequently, further structural properties of
(resp.
) and their modules may be established and realized in a constructive-computational way.

The author would very much like to thank the anonymous referee for his/her valuable comments, particularly for pointing out an error in constructing a monomial ordering in the proof of Theorem 2.3, which are quite helpful for improving the manuscript. The author is very grateful to professor Huishi Li for proposing the research topic, for very valuable discussions, and for his patient and meticulous guidance during preparing the manuscript.
