  • Epimorphisms in varieties of residuated structures 
    Bezhanishvili, Guram; Moraschini, Tommaso; Raftery, James G. (Elsevier, 2017-12)
    It is proved that epimorphisms are surjective in a range of varieties of residuated structures, including all varieties of Heyting or Brouwerian algebras of finite depth, and all varieties consisting of Gödel algebras, ...
  • Idempotent residuated structures : some category equivalences and their applications 
    Galatos, N.; Raftery, James G. (American Mathematical Society, 2015)
    This paper concerns residuated lattice-ordered idempotent commutative monoids that are subdirect products of chains. An algebra of this kind is a generalized Sugihara monoid (GSM) if it is generated by the lower bounds ...
