WebThe page on descriptive complexity theory in Wikipedia states the following: "First-order logic defines the class FO, corresponding to AC0, the languages recognized by polynomial-size circuits of bounded depth, which equals the languages recognized by a concurrent random access machine in constant time." WebFirst, a point of terminology: is this being used to mean a groupoid internal to Top (where we have a topology on the space of objects and on the space of morphisms) or a groupoid enriched in Top (where we only have a topology on each hom-set)? For no particular reason I bet he means the first. top notch automotive hawaii
