In his Preface to the Disquisitiones arithmeticaee, Gauss describes the disquisitiobes of the book as follows:. Although few of the results in these first sections are original, Gauss was the first mathematician to bring this material together and treat it in a systematic way. While recognising the primary importance of logical proof, Gauss also illustrates many theorems with numerical examples.

Before the Disquisitiones was published, number theory consisted of a collection of isolated theorems and conjectures. They must have appeared particularly cryptic to his contemporaries; they can now be read as containing the germs of the theories of L-functions and complex multiplicationin particular.

Many of the annotations given by Gauss are in effect announcements of further research of his own, some of which remained unpublished. For example, in section V, articleGauss summarized his calculations of class numbers of proper primitive binary quadratic forms, and conjectured that he had found all of them with class numbers 1, 2, and 3.

The Disquisitiones was one of the last mathematical works to be written in scholarly Latin an English translation was not published until Sometimes referred to as the class number problemthis more general question was eventually confirmed in[2] the specific question Gauss asked was confirmed by Landau in [3] for class number one. However, Gauss did not explicitly recognize the concept of a groupwhich is central to modern algebraso he did not use this term. This was later interpreted as the determination of imaginary quadratic number fields with even discriminant and class number 1,2 and 3, and extended to the case of odd discriminant.

There was a problem providing the content you requested Section VI includes two different primality tests. Articles containing Latin-language text. This page was last edited on 10 Septemberat Gauss brought the work of his predecessors together with his own original work into a systematic framework, filled in gaps, corrected unsound proofs, and extended the subject in numerous ways.

Carl Friedrich Gauss, tr. In other projects Wikimedia Commons. Views Read Edit View history. In section VII, articleGauss proved what can be interpreted as the first non-trivial case of the Riemann hypothesis for curves over finite fields the Hasse—Weil theorem. The logical structure of the Disquisitiones theorem statement followed by prooffollowed by corollaries set a standard for later texts.

The treatise paved the way for the theory of function fields over a finite field of constants. His own title for his subject was Higher Arithmetic. Section IV itself develops a proof of quadratic reciprocity ; Section V, which takes up over half arithmeticad the book, is a comprehensive analysis of binary and ternary quadratic forms.

The book is divided into seven sections, which are: Congruent Numbers in General Congruences of the First Degree Residues of Powers Congruences of the Second Degree Forms and Indeterminate Equations of the Second Degree Various Applications of the Preceding Discussions Equations Defining Sections of a Circle These sections are subdivided into numbered items, which sometimes state a theorem with proof, or otherwise develop a remark or thought. Although few of the results in these first sections are original, Gauss was the first mathematician to bring this material together and treat it in a systematic way. He also realized the importance of the property of unique factorization assured by the fundamental theorem of arithmetic , first studied by Euclid , which he restates and proves using modern tools.
