semisimple linear algebraic group; parabolic subgroup scheme; rational projective variety
It is shown that if \(G\) is a semisimple linear algebraic group over an algebraically closed field of characteristic \(p>3\) and \(P\) a parabolic subgroup scheme of \(G\), then \(G/P\) is a rational projective variety.
