Lattices of varieties of plactic-like monoids
Thomas Aird, Duarte Ribeiro
We study the equational theories and bases of meets and joins of several varieties of plactic-like monoids. Using those results, we construct sublattices of the lattice of varietie…

Plactic-like monoids arising from meets and joins of stalactic and taiga congruences
Thomas Aird, Duarte Ribeiro
We study the four plactic-like monoids that arise by taking the meets and joins of stalactic and taiga congruences. We obtain the combinatorial objects associated with the meet mon…
