The computation of Hecke-eigenforms of weight at least 2 is readily accomplished through the
theory of modular symbols as these Hecke-eigensystems occur in the cohomology of modular
curves. However, the same is not true for weight 1 modular forms which makes computing
the dimensions of such spaces difficult let alone the actual system of Hecke-eigenvalues.
Recently effective methods for computing such spaces have been introduced building on an
algorithm of Kevin Buzzard. In this talk, we present a different, p-adic approach towards
