This course examines key questions in the theory of numbers whose solution led to the development of modern abstract algebra. The basic notions of rings, fields, groups and field extensions will be developed and used to solve problems relating to the integers, as well as certain geometric problems that interested the ancient Greeks.
The integers, residue class arithmetic, theorems of Lagrange, Fermat and Euler, groups of units, Chinese remainder theorem, primitive roots, Gaussian integers, division algorithm and principal ideals in Z[i], quadratic residues, algebraic number fields, extensions, Eisenstein's test, ruler and compass constructions.
