We define a notion of unitarizability for weight modules over a generalized Weyl algebra (of rank one, with commutative coeffiecient ring R), which is assumed to carry an involution of the form X∗ = Y , R∗ ⊆ R. We prove that a weight module V is unitarizable iff it is isomorphic to its finitistic dual V . Using the classification of weight modules by Drozd, Guzner and Ovsienko, we obtain necess...

In this paper we consider Artinian modules over power series rings endowed with a Frobenius map. We describe a method for finding the set of all prime annihilators of submodules which are preserved by the given Frobenius map and on which the Frobenius map is not nilpotent. This extends the algorithm by Karl Schwede and the first author, which solved this problem for submodules of the injective ...

The impact of known good die (KGD) probability on multichip module (MCM) yield and cost has been modeled and systematically analyzed. The current work extends the researchers’ previous MCM modeling effort involving single chip populations (a single KGD probability) to modules containing complex, multiple chip populations. Most of the analysis is performed on modules with dual populations (that ...
