On unit root formulas for toric exponential sums
Exponential sum A-hypergeometric function
2011/1/19
Starting from a classical generating series for Bessel functions due to Schl¨omilch[4], we use Dwork’s relative dual theory to broadly generalize unit-root results of Dwork[3] on Kloosterman sums and ...
(k+1)-sums versus k-sums
(k+1)-sums k-sums
2010/11/23
Given $k\in \mathbb{N}$ and a subset $A=\{a_{1},...,a_{n}\}$ of $n$ integers, we define $S_{k}=S_{k}(A)=\{\sum_{I}a_{i}:I\in [n]^{(k)}\}$, i.e. $S_{k}$ is the set of integers that may be expressed as...
Line arrangements and direct sums of free groups
Line arrangements direct sums of free groups
2010/12/13
We show that if the fundamental groups of the complements of two line arrangements in the complex projective plane are isomorphic to the same direct sum of free groups, then the complements of the arr...
Loss of derivatives for systems of complex vector fields and sums of squares
Loss of derivatives for systems complex vector fields sums of squares
2010/11/29
We discuss, both for systems of complex vector fields and for sums of squares, the phenomenon discovered by Kohn of hypoellipticity with loss of derivatives.MSC: 32W05, 32W25, 32T25
Sums of five Almost Equal Prime Squares
2007/12/12
In this paper we sharpen Hua's result by proving that each sufficiently large integer $N$ congruent to 5 modulo 24 can be written as $$N=p_1^2+p_2^2+p_3^2+p_4^2+p_5^2, \mbox{ with } |p_j-\sqrt{N/5}| \...
Maximal Moment Inequality for Partial Sums of Strong Mixing Sequences and Application
strong mixing maximal moment inequality fixed design regression model weight function estimate asymptotic normality
2007/12/10
Some maximal moment inequalities for partial sums of the strong mixing random variable sequence are established. These inequalities use moment sums as up-boundary and improve the corresponding ones ob...
