Soient (\mathbf{g}) une algรจbre de Lie semi-simple et (\mathbf{n}^{+})une sous-algรจbre nilpotente maximale de g. L'algรจbre enveloppante quantifiรฉe (\check{U}{4}(\mathbf{g})) et sa sous-algรจbre (U{q}\left(\mathbf{n}^{+}\right)). Nous donnons l'ensemble des รฉlรฉments normaux de (U_{q}\left(\mathbf{n}^{+}\right)). Nous montrons que tout idรฉal de (U_{4}\left(\mathbf{n}^{+}\right))peut รชtre engendrรฉ par une suite normalisante.

Let (\mathbf{g}) be a semi-simple Lie algebra with maximal nilpotent subalgebra (\mathbf{n}^{+}). Let (\breve{U}{q}(\mathbf{g})) and (U{q}\left(\mathbf{n}^{+}\right))be the quantized enveloping algebras. We describe the set of normal elements of (U_{4}\left(\mathbf{n}^{+}\right)). We prove that each ideal of (U_{4}\left(\mathbf{n}^{+}\right))can be generated by a normal sequence. ci 1995 Academic Press. Inc.

It is shown that, for a class of unital C\*-algebras including purely infinite simple C\*-algebras, real rank zero simple AT algebras, and AF algebras, if u and v are almost commuting unitaries where u has trivial K 1 -class, v has full spectrum, and a certain K 0 -valued obstruction associated to t
