Sastry, Pramathanath; Seshadri, C. S. Geometric reductivity – a quotient space approach. (English) Zbl 1360.14119 J. Ramanujan Math. Soc. 26, No. 4, 415-477 (2011). Summary: We give another proof that a reductive algebraic group is geometrically reductive. We show that a quotient of the semi-stable locus (by a linear action of a reductive algebraic group on a projective scheme) exists, and from this Haboush’s Theorem (Mumford’s Conjecture) follows.
