Let G be any group acting on the Weyl algebra W β«ήβ¬ . We shall propose a 1 Ε½ . G method for finding explicit generators of the ring of invariants W β«ήβ¬ . This 1 method can be generalized to the case of the ring of invariants of an almost normalizing extension R over a commutative ring C under the li
