  Carl Friedrich Gauss - Wikipedia, the free encyclopedia
Gauss was a child prodigy, of whom there are many anecdotes pertaining to his astounding precocity while a mere toddler, and made his first ground-breaking mathematical discoveries while still a teenager.
Gauss was so pleased by this result that he requested that a regular heptadecagon be inscribed on his tombstone.
Gauss predicted correctly the position at which it could be found again, and it was rediscovered by Franz Xaver von Zach on December 31, 1801 in Gotha, and one day later by Heinrich Olbers in Bremen.

 Gaussian period - Wikipedia, the free encyclopedia
Squaring P as a sum leads to a counting problem, about how many quadratic residues are followed by quadratic residues, that can be solved by elementary methods (as we would now say, it computes a local zeta-function, for a curve that is a conic).
(Gauss sums are in a sense the finite field analogues of the gamma function.)
Gauss sums can therefore be written as linear combinations of Gaussian periods, with coefficients χ(a); the converse is also true, as a consequence of the orthogonality relations for the group (Z/nZ)

Gauss sums, Jacobi sums and p-ranks of cyclic difference sets
Stickelberger's theorem for Gauss sums is used to reduce the computation of these 2-ranks to a problem of counting certain cyclic binary strings of length d.
This counting problem is then solved combinatorially, with the aid of the transfer matrix method.

We consider Gauss sums associated to functions $T\to Q/Z$ which satisfy some sort of "quadratic'' property and investigate their elementary properties.
These properties and a Gauss sum formula from the nineteenth century due to Dirichlet enable us to give elementary proofs of many standard results.
We derive the Milgram Gauss sum formula computing the signature mod 8 of a non{--}singular bilinear form over $Q$ and its generalization to non{--}even lattices.

The first 2 chapters are on arithmetic functions, asymptotic formulas for averaging sums, using elementary methods like Euler-Maclaurin formula.This lay down the foundation for further discussion in later chapters, where complex analysis is involved in the investigation.
Since the purpose of this chapter is to prepare for the proof of Dirichlet's theorem and introduction of Gauss sums, the character theory is developed just to the point which is all that's needed.
The complete analytic proof, using contour integration to evaluate explicitly the quadratic Gauss sums, is a marvellous illustration of how truth about integers can be obtained by crossing into the complex domains.

 Reciprocity Laws
Gauss and Jacobi sums are introduced and studied, and we also present a short discussion of Eisenstein sums.
Apart from giving the proofs of rational quartic reciprocity by comparing the splitting of primes in certain extensions, of the full quartic reciprocity law in Z[i] using Gauss sums, and of the quartic reciprocity law in the field of eighth roots of unity, we discuss several applications.
The proof uses the octic reciprocity law, whose proof is based on octic elliptic Gauss sums.

This book is concerned with two areas of mathematics, at first sight disjoint, and with some of the analogies and interactions between them.
These areas are the theory of linear differential equations in one complex variable with polynomial coefficients, and the theory of one parameter families of exponential sums over finite fields.
The final part of the book is devoted to comparison theorems relating G and G of suitably "corresponding" situations, which provide a systematic explanation of the remarkable "coincidences" found "by hand" in the hypergeometric case.
