group theory applied to the solution of algebraic equations
Source: WordNetA treatment of Galois theory along these lines by Kaplansky was influential in the recognition of the general structure here. Source: Internet
Shows how generalisations of Galois theory lead to Galois groupoids. Source: Internet
Galois theory allows to prove that, if the angle is not a multiple of 3°, non-real cube roots are unavoidable. Source: Internet
His contributions include the invention of a topological form of the Abel–Ruffini theorem and the initial development of some of the consequent ideas, a work which resulted in the creation of the field of topological Galois theory in the 1960s. Source: Internet

See that article for a number of examples: the case of Galois theory of course is a leading one. Source: Internet
