چکیده

Recent developments in the theory and application of the HardyLittlewood method are discussed, concentrating on aspects associated with diagonal diophantine problems. Recent efficient differencing methods for estimating mean values of exponential sums are described first, concentrating on developments involving smooth Weyl sums. Next, arithmetic variants of classical inequalities of Bessel and Cauchy-Schwarz are discussed. Finally, some emerging connections between the circle method and arithmetic geometry are mentioned. 2000 Mathematics Subject Classification: 11P55, 11L07, 11P05, 11D72, 14G05.

Translation invariance, exponential sums, and Waring’s problem

We describe mean value estimates for exponential sums of degree exceeding 2 that approach those conjectured to be best possible. The vehicle for this recent progress is the efficient congruencing method, which iteratively exploits the translation invariance of associated systems of Diophantine equations to derive powerful congruence constraints on the underlying variables. There are application...

On Weyl’s Inequality, Hua’s Lemma, and Exponential Sums over Binary Forms

1. Introduction. The remarkable success enjoyed by the Hardy-Littlewood method in its application to diagonal diophantine problems rests in large part on the theory of exponential sums in a single variable. Following almost a century of intense investigations , the latter body of knowledge has reached a mature state that, although falling short of what is expected to be true, nonetheless suffic...

Upper Bounds for the Number of Solutions of a Diophantine Equation

We give upper bound estimates for the number of solutions of a certain diophantine equation. Our results can be applied to obtain new lower bound estimates for the L1-norm of certain exponential sums.

T-adic Exponential Sums over Finite Fields

T -adic exponential sums associated to a Laurent polynomial f are introduced. They interpolate all classical p-power order exponential sums associated to f . The Hodge bound for the Newton polygon of L-functions of T -adic exponential sums is established. This bound enables us to determine, for all m, the Newton polygons of Lfunctions of p-power order exponential sums associated to an f which i...

Breaking classical convexity in Waring's problem: Sums of cubes and quasi-diagonal behaviour

The natural interpretation of even moments of exponential sums, in terms of the number of solutions of certain underlying diophantine equations, permits a rich interplay to be developed between simple analytic inequalities, and estimates for those even moments. This interplay is in large part responsible for the remarkable success enjoyed by the Hardy-Littlewood method in its application to num...
