Booknews

Provides summary of field theory that emphasizes refinements and extensions achieved in recent studies. It describes canonical fundamental units of certain classes of pure cubic fields, proves Knesser's theorem on torsion groups of separable field extensions, establishes a theorem that provides necessary and sufficient conditions for the Galois group of a binomial Xn-a to be abelian, shows the result of the degrees of sums in a separable field extension.
