The study of monadic algebraic structures and fuzzy logic has evolved into a vibrant research area that bridges abstract algebra with the nuanced reasoning of uncertainty. By incorporating unary ...

We solve a problem of Friedman by showing the existence of a logic stronger than first-order logic even for countable models, but still satisfying the general compactness theorem, assuming e.g. the ...

Cylindrical Algebraic Decomposition (CAD) is a pivotal algorithmic technique in real algebraic geometry, instrumental in resolving problems expressed in a first‐order language over the reals. By ...

We associate the semantic game with chance moves conceived by Blinov with Blamey's partial logic. We give some equivalent alternatives to the semantic game, some of which are with a third player, ...
