On the generalization of Christol's theorem to domains of finite type over finite fields
Lian Duan, Chunlin Wang
We generalize Christol's theorem---which characterizes algebraic power series over a finite field in terms of automatic coefficient sequences---to completions of domains of finite…
Expansions in completions of global function fields
Chunlin Wang
It is well known that any power series over a finite field represents a rational function if and only if its sequence of coefficients is ultimately periodic. The famous Christol's…
On covering systems of polynomial rings over finite fields
Huixi Li, Biao Wang, Chunlin Wang +1
In 1950, Erdős posed a question known as the minimum modulus problem on covering systems for , which asked whether the minimum modulus of a covering system with distinc…
Distribution of residues of an algebraic number modulo ideals of degree one
Chunlin Wang
Let be an irreducible polynomial with integer coefficients of degree at least two. Hooley proved that the roots of the congruence equation is uniformly…
Newton polygons for -functions of generalized Kloosterman sums
Chunlin Wang, Liping Yang
In this paper, we study the Newton polygons for the -functions of -variable generalized Kloosterman sums. Generally, the Newton polygon has a topological lower bound, called…
-functions for families of generalized Kloosterman sums and -adic differential equations
Chunlin Wang, Liping Yang
In this paper, we focus on a family of generalized Kloosterman sums over the torus. With a few changes to Haessig and Sperber's construction, we derive some relative -adic cohom…
