Rational Points on Igusa Curves and L-functions of Symmetric Representations, by Am'ilcar Pacheco

This paper has appeared in J. Number Theory 58 (1996), no. 2, 343-360, and so the dvi version has been removed. The purpose of this paper it to give a new and explicit proof of a result due to D. Ulmer in which he computes the $L$-functions of symmetric representations of the first \'etale cohomology group of universal elliptic curves over Igusa curves in terms of Hecke polynomials.
