Maximal theories of product logic [PDF]

EUSFLAT AGOP 2023. Lecture Notes in Computer Science, vol 14069. Springer, Cham (2023), 2023
Product logic is one of the main fuzzy logics arising from a continuous t-norm, and its equivalent algebraic semantics is the variety of product algebras. In this contribution, we study maximal filters of product algebras, and their relation with product hoops. The latter constitute the variety of 0-free subreducts of product algebras.
