Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X∕H], whereXis a projective scheme andHis a linear algebraic group with internally graded unipotent radical acting linearly onX, in such a way that each stratum [S∕H] has a geometric quotientS∕H. This leads to stratifications of moduli stacks (for example, sheaves over a projective scheme) such that each stratum has a coarse moduli space.
