In modern algebra: Rings in number theory Leopold Kronecker used rings of algebraic integers. (An algebraic integer is a complex number satisfying an algebraic equation of the form x n + a 1 x n−1 + + a n = 0 where the coefficients a 1, , a n are integers.) Their work introduced the important concept of . Algebraic number theory is a branch of number theory that uses the techniques of abstract algebra to study the integers, rational numbers, and their -theoretic questions are expressed in terms of properties of algebraic objects such as algebraic number fields and their rings of integers, finite fields, and function properties, such as whether a ring admits.

Algebraic number theory involves using techniques from (mostly commutative) algebra and nite group theory to gain a deeper understanding of the arithmetic of number elds and related objects (e.g., functions elds, elliptic curves, etc.). The main objects that we study in this book are number elds, rings of integers of. An algebraic number ﬁeld is a ﬁnite extension of Q; an algebraic number is an element of an algebraic number ﬁeld. Algebraic number theory studies the arithmetic of algebraic number ﬁelds — the ring of integers in the number ﬁeld, the ideals and units in the ring of integers, the extent to which unique factorization holds, and so on.

Algebraic number theory is about employing unique factorisation in rings larger than the integers. The classical cases are the quadratic integers and the cyclotomic integers. They came with elaborate theories to deal with the fact that unique factorisation does not always hold.5/5.   Updated to reflect current research, Algebraic Number Theory and Fermat’s Last Theorem, Fourth Edition introduces fundamental ideas of algebraic numbers and explores one of the most intriguing stories in the history of mathematics—the quest for a proof of Fermat’s Last Theorem. The authors use this celebrated theorem to motivate a general study of the theory of algebraic numbers Cited by:

edition. In algebraic number theory, an algebraic integer is a complex number that is a root of some monic polynomial with coefficients in ℤ. The set of all algebraic integers, A, is closed under addition, subtraction and multiplication and therefore is a commutative subring of the complex numbers.

The ring A is the integral closure of regular integers ℤ in complex numbers. The ring of integers of a number. The main objects that we study in algebraic number theory are number ﬁelds, rings of integers of number ﬁelds, unit groups, ideal class groups,norms, traces, discriminants, prime ideals, Hilbert and other class ﬁelds and associated reciprocity laws, zeta and L-functions, and algorithms for computing each of the Size: KB.
