2500. Nikolaos Galatos, Isis A. Gallardo Decidability of distributive l-pregroups E-mail: Submission date: 19 October 2023 Abstract: We show that every distributive lattice-ordered pregroup can be embedded into a functional algebra over an integral chain, thus improving the existing Cayley/Holland-style embedding theorem. We use this to show that the variety of all distributive lattice-ordered pregroups is generated by the single functional algebra on the integers. Finally, we show that the equational theory of the variety is decidable. Mathematics Subject Classification: Keywords and phrases: |
