Galois representations and modularity for twisted moments of Kloosterman sums

Zi Li Lim, Fang-Ting Tu, Jeng-Daw Yu

Associated with the classical Kloosterman sums, we consider the quadratic twisted symmetric power moments. We investigate the cohomological properties and construct the motives ove…

Structure of the cuspidal rational torsion subgroup of J_1(p^n)

Yifan Yang, Jeng-Daw Yu

In this article, we determine the structure of the $p$ -primary subgroup of the cuspidal rational torsion subgroup of the Jacobian $J_{1} (p^{n})$ of the modular curve $X_{1} (p^{n})$ for a r…
