Cup products and L-values of cusp forms

Romyar T. Sharifi

Research output: Contribution to journalArticlepeer-review


In this note, we describe a conjecture that, for an odd prime p, relates special values of a cup product pairing on cyclotomic p-units in Q(μp) to the L-values of newforms satisfying modulo p congruences with Eisenstein series for SL2(Z).
