Francesc d'A. Sales Vallès
Francesc d'A. Sales Vallès (1914-2005) was a professor of Probability and Statistics at the Faculty of Mathematics of the University of Barcelona. During the 1970s and 1980s he promoted, besides his original field of research, the study of ordered algebraic structures (lattices, Boolean algebras, etc.) and the study and teaching of mathematical logic in the mathematics curriculum. Several dissertations on related topics were done under his supervision, and this eventually led to the establishment of several research groups in fuzzy set theory, many-valued logic, and algebraic logic. These groups have continued to expand up to this date, mainly at the University of Barcelona, at the Polytechnic University of Catalonia, and at the Research Institute on Artificial Intelligence (IIIA-CSIC) based in Bellaterrra (Barcelona, Spain) and currently produce a lot of research in these and neighbouring areas.
