Carl Friedrich Gauss’s textbook, Disquisitiones arithmeticae, published in ( Latin), remains to this day a true masterpiece of mathematical examination.

Gauss also states, “When confronting many difficult problems, derivations have been suppressed for the sake of brevity when readers refer to this work.

The Disquisitiones was one of the last mathematical works to be written in scholarly Latin an English translation was not published until 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.

It appears that the first and only translation into English was by Arthur A. It is notable for having a revolutionary impact on the field of number theory as it not only turned the field truly rigorous and systematic but also paved the path for modern number theory. This includes reference requests – also see our lists of recommended books and free online resources. The eighth section was finally published as a treatise entitled “general investigations on congruences”, and in it Gauss discussed congruences of arbitrary degree.

Although few of the engliwh in these first sections are original, Gauss was the first mathematician to bring this material together and treat it in a systematic way. TeX all the things Chrome extension configure inline math to use [ ; ; ] delimiters.


Clarke in second editionGoogle Books previewso it is still under copyright and unlikely to be found online. His own title for his subject was Higher Arithmetic. It’s worth notice since Gauss attacked the problem of general congruences from a standpoint closely related to that taken later by DedekindGaloisand Emil Artin.

Few modern authors can match the depth and breadth of Euler, and there is actually not much in the book that is unrigorous. Everything about X – every Wednesday. Please be polite and civil when commenting, and always follow reddiquette.

The Disquisitiones covers both aeithmeticae number theory and parts of the area of mathematics now called algebraic number theory.

The Disquisitiones Arithmeticae Latin for “Arithmetical Investigations” is a textbook of number theory written in Latin [1] by Carl Friedrich Arithmetivae in when Gauss was 21 and first published in when he was Carl Friedrich Gauss, tr.

Please read the FAQ before posting. Ideas unique to that treatise are clear recognition of the importance of the Frobenius morphismand a version of Hensel’s lemma.

The logical enylish of the Disquisitiones theorem statement followed by prooffollowed by corollaries set a standard for later texts. Log in or sign up in seconds.

The inquiries which this volume will investigate pertain to that part of Mathematics which concerns itself with integers. 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 disquisiiones.

General political debate is not permitted. It has been called the most influential textbook after Euclid’s Elements.

In other projects Wikimedia Commons. I looked around online and most of the proofs involved either really messy calculations or cyclotomic polynomials, which we hadn’t covered yet, but I found Gauss’s original proof in the preview 81, p.


Gauss started to write an eighth section on disquisitionew order congruences, but he did not complete this, and it was published separately after his death. I was recently looking at Euler’s Introduction to Analysis of the Infinite tr. Blanton, and it appears a great book to give to even today’s interested high-school or college student. Many of the annotations given by Gauss are in effect announcements of further research of his own, some of which remained unpublished.


From Wikipedia, the free encyclopedia.

These sections are subdivided into numbered fisquisitiones, which sometimes state a theorem with proof, or otherwise develop a remark or thought. However, Gauss did not explicitly recognize the concept of a groupwhich is central to modern algebraso he did not use this term.

Section VI includes two different primality tests.

Submit a new link. 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. The treatise paved the way for the theory of function fields over a finite field of constants. The Google Books preview is actually pretty good – for instance, in my number theory class, I was stuck on a homework problem that asked us to prove that the sum of the primitive roots of p is mobius p Here is a more recent thread with book recommendations.

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.
