Improvements of the Weil bound for Artin-Schreier curves
(Springer, 2011-10)
For the Artin-Schreier curve y q − y = f(x) defined over a finite field Fq of q elements, the celebrated Weil bound for the number of Fq r -rational points can be sharp, especially in super-singular cases and when r is ...

L-functions of symmetric powers of the generalized Airy family of exponential sums
(2011-12)
This paper looks at the L-function of the kth symmetric power of the -sheaf Aif over the affine line associated to the generalized Airy family of exponential sums. Using ℓ-adic techniques, we compute the degree of this ...
