Various quantum algebras are shown to be catenary, i.e., all saturated
chains of prime ideals between any two fixed primes have the same len
gth. Further, Tauvel's formula relating the height of a prime ideal to
the Gelfand-Kirillov dimension of the corresponding factor ring is es
tablished. These results are obtained for coordinate rings of quantum
affine spaces, for quantized Weyl algebras, and for coordinate rings o
f complex quantum general linear groups, as well as for quantized enve
loping algebras of maximal nilpotent subalgebras of semisimple complex
Lie algebras.
