A Tenth Hilbert Problem-like Result: The Decidability of MLS with Unordered Cartesian Product
arXiv:1902.10511
Abstract
Using the technique of formative processes, I solve the decidability problem of MLS with unordered cartesian product in the positive. Moreover I give a pure combinatorial description of the satisfiable MLS with unordered cartesian product-formulas for a given number of variables.
