Böckle, Gebhard (ed.) et al., Computations with modular forms. Proceedings of a summer school and conference, Heidelberg, Germany, August–September 2011. Cham: Springer (ISBN 978-3-319-03846-9/hbk; 978-3-319-03847-6/ebook). Contributions in Mathematical and Computational Sciences 6, 257-277 (2014).
Summary: The paper contains a numerical study of congruences modulo prime powers between newforms and Eisenstein series at prime levels and with equal weights. We study the upper bound on the exponent of the congruence and formulate several observations based on the results of our computations.
