Cusp forms as p-adic limits [PDF]
Journal of Number Theory, 2022 Ahlgren and Samart relate three cusp forms with complex multiplication to certain weakly holomorphic modular forms using $p$-adic bounds related to their Fourier coefficients. In these three examples, their result strengthens a theorem of Guerzhoy, Kent, and Ono which pairs certain CM forms with weakly holomorphic modular forms via $p$-adic limits ...

Exceeding the Forming Limit Curve with Deep Drawing Followed by Electromagnetic Calibration [PDF]
, 2012 We show that the materials quasi-static forming limit curve (FLC) can be exceeded by the process chain composed of deep drawing followed by electromagnetic forming. We form circular cups as close as possible to the FLC by deep drawing.
