... The satisfiability problem of two-variable logic FO2 was shown to be NEXPTIME-complete in [9]. The extension of two-variable logic with counting quantifiers, FOC2 , was proved decidable in [10,21], and it was subsequently shown to be NEXPTIME-complete in [22]. Research on extensions and variants of ...

Any solution x2 to the congruence modulo 72 must also be a solution modulo 7, hence of the form x2 = x1 + 7y = ±3 + ...

It follows that X is uncountable: if X were at most countable, then X + r (which is in bijection with X via the function x 7→ x + r) must be at most countable for every rational r, and there are only countably many rationals so [0, 1] would be a countable union of at mo ...
