Geometric invariant theory is concerned with constructing quotients of a variety X by an action of an algebraic group G. Optimally, in the case of a geometric quotient, points of the quotient parametrize orbits. This talk recalls these notions and then turns to the case that G is connected and solvable, presenting an algorithm for constructing a nonempty open subset U of X and a geometric quotient of U. The quotient is in fact even better than being geometric.
