✦ Synopsis


We describe an algorithmic test, using the "standard polynomial identity" (and elementary computational commutative algebra), for determining whether or not a finitely presented associative algebra has an irreducible n-dimensional representation. When n-dimensional irreducible representations do exist, our proposed procedure can (in principle) produce explicit constructions.

We formulate an algorithm for calculating a representation by unipotent matrices over the integers of a finitely-generated torsion-free nilpotent group given by a polycyclic presentation. The algorithm works along a polycyclic series of the group, each step extending a representation of an element o

Quantized enveloping algebras U α’„ and their representations provide natural settings for the action of the corresponding braid groups. Objects of particular Ε½ . interest are the zero weight spaces of U α’„ -modules since they are stable under the Ε½ . braid group action. We show that for α’„ s ᒐ α’‰ there
