Bounds on special values of L-functions of elliptic curves ...

We study a certain Artin–Schreier family of elliptic curves over the function field . We prove an asymptotic estimate on the special values of their L-function in terms of the degree of their conductor; we show that the special values are, in a sense, 'asymptotically as large as possible'. We also provide an explicit expression for their L-function. The proof of the main result uses this ...
