Galois Theory

This text offers a clear, efficient exposition of Galois Theory with exercises and complete proofs. Topics include: Cardano''s formulas; the Fundamental Theorem; Galois'' Great Theorem (solvability for radicals of a polynomial is equivalent to solvability of its Galois Group); and computation of Galois group of cubics and quartics. There are appendices on group theory and on ruler-compass construc...
