Algebra and Number Theory

In the two-volume set ‘A Selection of Highlights’ we present basics of mathematics in an exciting and pedagogically sound way. This volume examines fundamental results in Algebra and Number Theory along with their proofs and their history. In the second edition, we include additional material on perfect and triangular numbers. We also added new sections on elementary Group Theory, p-adic numbers, and Galois Theory.

• A true collection of mathematical gems in Algebra and Number Theory, including the integers, the reals, and the complex numbers, along with beautiful results from Galois Theory and associated geometric applications.
• Valuable for lecturers, teachers and students of mathematics as well as for all who are mathematically interested.

Revised second edition updates:

• A new simple proof of the Fundamental Theorem of Arithmetic
• Proves the fundamentals of group theory including, the Lagrange, isomorphism, and Sylow theorems.
• New material on p-adic integers in number theory.
