Ib Troen,Søren Larsen,Torben MikkelsenThe hypothesis in Theorem 40 that . contain certain roots of unity can be dropped, but we give a preliminary discussion from group theory before proving this.

Nadezda Sinik,Edita Loncar,Sonja VidicRecall Theorem A21: If . is a group having a solvable normal subgroup . such that . is solvable, then . is solvable. Here is the improved version of Theorem 40 which needs no assumption about roots of unity.

Air Pollution Modeling and Its Application XWe prove the converse of Theorem 53 (which holds only in characteristic 0): solvability of the Galois group implies solvability by radicals of the polynomial. We begin with some lemmas; the first one has a quaint name signifying its use as a device to get around the possible absence of roots of unity in the ground field.
