Q
- Quasi-algebraic closure
- The topic of quasi-algebraic closure, i.e. solubility guaranteed by a number of variables polynomial in the degree of an equation, grew out of studies of the Brauer group and the Chevalley–Warning theorem. It stalled in the face of counterexamples; but see Ax–Kochen theorem from mathematical logic.
