Constructing irreducible representations of finitely presented algebras

Edward S. Letzter

By combining well-known techniques from both noncommutative algebra and computational commutative algebra, we observe that an algorithmic approach can be applied to the study of ir…

Module Extensions Over Classical Lie Superalgebras

E. S. Letzter

We study certain filtrations of indecomposable injective modules over classical Lie superalgebras, applying a general approach for noetherian rings developed by Brown, Jategaonkar,…

Noetherian Centralizing Hopf Algebra Extensions and Finite Morphisms of Quantum Groups

E. S. Letzter

Let $A \subset H$ be a finite centralizing extension of noetherian Hopf algebras, and let $X$ denote the group of characters of $H$ that restrict to the augmentation map on $A$ . Ou…

Quantum n-space as a quotient of classical n-space

K. R. Goodearl, E. S. Letzter

Let $A$ denote the commutative polynomial ring in $n$ variables, over an algebraically closed field $k$ , and let $R$ denote the standard multiparameter quantization of $A$ determin…
