A Lie Algebra Method for Rational Parametrization of Severi-Brauer Surfaces
Willem A. de Graaf, Michael Harrison, Jana Pilnikova +1
It is well-known that a Severi-Brauer surface has a rational point if and only if it is isomorphic to the projective plane. Given a Severi-Brauer surface, we study the problem to d…
