In this paper we consider the consistency problem of temporal or spatial qualitive constraint networks. A new encoding making it possible to represent and solve this problem in th...
We present a uniform relational framework for developing proof systems for theories of manyvaluedness that may have the form of a logical system, of a class of algebra or of an in...
Physical design for object-oriented databases is still in its infancy. Implementation decisions often intrude into the conceptual design (such as inverse links and object decompos...
In our paper "Uniformity and the Taylor expansion of ordinary lambda-terms" (with Laurent Regnier), we studied a translation of lambda-terms as infinite linear combinati...
We present a general theory of Gifford-style type and effect annotations, where effect annotations are sets of effects. Generality is achieved by recourse to the theory of algebra...
