## COURSE DESCRIPTION

WHAT IS MATH 104A? This is the first course in algebraic number theory for undergraduate students with background in abstract algebra. The course will focus on the arithmetic of number fields and their rings of algebraic integers. We will cover most of the material in Chapters 1 - 6 of the textbook.

TEXT
