Factorised representations of query results: size bounds and readability
We introduce a representation system for relational data based on algebraic factorisation using distributivity of product over union and commutativity of product and union. We giv...

Algebraic Structures for Bipolar Constraint-Based Reasoning
The representation of both scales of cost and scales of benefit is very natural in a decision-making problem: scales of evaluation of decisions are often bipolar. The aim of this ...

State-Aware Performance Analysis with eXtended Stochastic Probes
We define a mechanism for specifying performance queries which combine instantaneous observations of model states and finite sequences of observations of model activities. We reali...

An algorithm for finding all preprojective components of the Auslander-Reiten quiver
Abstract. The Auslander-Reiten quiver of a finite-dimensional associative algebra A encodes information about the indecomposable finite-dimensional representations of A and their h...
