We introduce the notion of a candidate for “multiple valued universal constructions” and define stable functors (which generalise functors with left adjoints) in terms of fac...
Large and sparse rational eigenproblems where the rational term is of low rank k arise in vibrations of fluid–solid structures and of plates with elastically attached loads. Exp...
We consider parallel algorithms for computing the Hermite normal form of matrices over Euclidean rings. We use standard types of reduction methods which are the basis of many algor...
We consider control systems of the type x = Ax+(t)bu, where u R, (A, b) is a controllable pair and is an unknown time-varying signal with values in [0, 1] satisfying a permanent...
In data-integration systems, information sources often have various constraints such as “all houses stored at a source have a unique address.” These constraints are very usefu...
