The weak cancellation property is proved to be the difference between cancellation and pseudocomplementation, so it gives a new axiomatization of product logic and ΠMTL. By adding this property, some new fuzzy logics (propositional and first-order) are defined and studied obtaining some results about their (finite) strong standard completeness and other logical and algebraic properties.}, URL = {http://logcom.oxfordjournals.org/content/16/4/423.abstract}, eprint = {http://logcom.oxfordjournals.org/content/16/4/423.full.pdf+html}, journal = {Journal of Logic and Computation} }
