Hodge-Stickelberger polygons for L-functions of exponential sums of P(x^s)

Regis Blache, Eric Ferard, Hui June Zhu

Let P(x) be a one-variable Laurent polynomial of degree (d_1,d_2) over a finite field of characteristic p. For any fixed positive integer s not divisible by p, we prove that the (n…

Newton polygons for twisted exponential sums and polynomials

Regis Blache, Eric Ferard

We study the -adic absolute value of the roots of the -functions associated to certain twisted character sums, and additive character sums associated to polynomials ,…
