Galois Theory of Equations,(.) = 0. To say that an equation is solvable by radicals means roughly that its roots can be obtained from the coefficients by rational operations and root extractions. A criterion for this was given by Galois after Abel and Ruffini had proved that the general equation of the fifth degree is not sol

Abelian Extensions,numbers and we shall determine their dimensionalities and Galois groups. Next we shall consider Kummer extensions, which are obtained by adjoining the roots of a finite number of pure equations .. . to a field containing . distinct .-th roots of 1. Finally, we shall study the so-called abelian .exte

Structure Theory of Fields,aic extensions has been made in Chapter I. In this chapter our primary concern will be with infinite dimensional extensions and we shall begin again with the algebraic ones. We define algebraically closed fields and prove the existence of an algebraic closure of any field. We shall extend the classi
