The field is principally devoted to consideration of direct additivr over typically the integers, that is, determining the structure of hA from the structure of A: For this reason, proofs include many “unnecessary” and “obvious” steps; this is by design.
Additive number theory is in large part the study of bases of finite order. The classical questions associated with these bases are Waring’s problem and the Goldbach conjecture.

From Wikipedia, the free encyclopedia. Many of these problems are studied using the tools from the Hardy-Littlewood circle method and from sieve methods. Additive number theory has close ties to combinatorial number theory and the geometry of numbers. In general, the set A of nonnegative integers is called an additive basis of order h if every nonnegative integer can be written as numver sum of h not necessarily distinct elements of A.
In the case of the integers, the classical Freiman’s theorem provides a potent partial answer to this question in terms of multi-dimensional arithmetic progressions. Every nonnegative integer is the afditive of four squares.
Additive number theory
Unlike problems related to classical bases, as described above, this sub-area often deals with finite subsets rather than infinite ones. Selected pages Title Page. For example, a set A is called a minimal asymptotic basis of order h if A is an asymptotic basis of order h but no proper subset of A is an asymptotic basis of order h.
Commutative Algebra David Eisenbud. The book also includes a large number of exercises For example, Vinogradov proved that every sufficiently large odd number is the sum of three primes, and so every sufficiently large even integer is the sum of four primes.

The archetypical theorem in additive number theory is due to Lagrange: Cauchy’s polygonal number theorem, Linnik’s theorem on sums of cubes, Hilbert’s proof of Waring’s problem, the Hardy-Littlewood asymptotic formula for the number of representations of an integer as the sum of positive kth powers, Shnirel’man’s theorem that every integer greater than one is the sum of a bounded number of primes, Vinogradov’s theorem on sums of three primes, and Chen’s theorem that every sufficiently large even integer is the sum of a prime and a number that is either prime or the product of two primes.
In number theorythe specialty additive number theory studies subsets of integers and their behavior under addition. Review quote From the reviews: Check out the top books of the year on our page Best Books of The classical bases are the squares, cubes, and higher powers; the polygonal numbers; and the prime numbers.
In general, the set A of nonnegative integers is called an additive basis of order h if every nonnegative integer can be written as the sum of h not necessarily distinct elements of A.
The book is also an introduction to the circle method and sieve methods, which are the principal tools used to study the classical bases. Riemannian Geometry Peter Petersen.

Ill additive number theory, not for experts who already know it. This book is intended for students who want to lel? Topology and Geometry Glen E. Graph Theory Adrian Bondy. Table of contents I Waring’s problem. The set A is called a basis offinite order if A is a basis of order h for some positive integer h. More abstractly, the field of “additive number theory” includes the study of abelian groups and commutative semigroups with thelry operation of addition.
Nathanson No preview available – A typical question is what is the structure of a pair of subsets whose sumset has small cardinality in relation to A and B. A novel feature of the book, and one that makes it very easy to read, is that all the calculations are written out thfory full – there are no steps ‘left to the adcitive.
Dispatched from the UK in 3 business days When will my order arrive? Weyl theorh The purpose of this book is to describe the classical problems adxitive additive number theory and to introduce the circle method and the sieve method, which are the basic analytical and combinatorial tools used to attack these problems. This page was last edited on 11 Decemberat Additive number theory is in large part the study of bases of finite order.
