Newton Polygons for a Variant of the Kloosterman Family
We study the p-adic valuations of roots of L-functions associated with certain families of exponential sums of Laurent polynomials. The families we consider are reflection and Kloosterman variants of diagonal polynomials. Using decomposition theorems of Wan, we determine the Newton and Hodge polygons of a non-degenerate Laurent polynomial in one of these families.
