Symmetric power L-functions of a weighted hyper-Kloosterman family
Abstract
As a natural generalization of the classical hyper-Kloosterman family studied by D. Haessig and S. Sperber, we study the k-th symmetric power L-functions attached to a weighted hyper-Kloosterman family Kln,m(t;x1,···,xn)=x1m+x2···+xn+t/(x1x2··· xn). Under suitable conditions, we determine the bounds of degrees of these L-functions and prove that their q-adic Newton polygons admit uniform lower bounds.
