AN ALGEBRAIC APPROACH TO NON-CLASSICAL LOGICS Josep Maria Font (Barcelona) In this talk I will highlight (some of) the key points in H. Rasiowa's approach to the algebraic study of non-classical logics, trace their roots into the Polish tradition, and survey some more recent developments in the field of abstract algebraic logic that can be somehow connected to her work, either for being its generalizations, or for setting up alternative approaches to the issue of finding relationships between logic and algebra.
