Counting level-raising congruences using modular representation theory

Jaclyn Lang, Robert Pollack, Preston Wake

We introduce a new method for studying mod- $ℓ$ congruences between eigenforms through the modular representation theory of $PGL_{2} (F_{p})$ . When $p\equiv \pm 1 \p…

Modular analogs of character formulas and minimal lifts of modular forms

Patrick B. Allen, Preston Wake

If $f$ is a mod- $3$ eigenform of weight 2 and level $Γ_{0} (ℓ^{2})$ for a prime $ℓ$ such that $ℓ \equiv - 1 (mod 3)$ , and $ℓ$ is a vexing prime for $f$ , we show that there i…

Corrigendum to "Modular Gelfand pairs and multiplicity-free representations"

Patrick Allen, Preston Wake, Robin Zhang

Some of the multiplicity-freeness results in ``Modular Gelfand pairs and multiplicity-free representations'' are stated in overly broad generality. We provide counterexamples and p…

Iwasawa invariants in residually reducible Hida families

Robert Pollack, Preston Wake

We study the variation of $μ$ -invariants of modular forms in a cuspidal Hida family in the case that the family intersects an Eisenstein family. We allow for intersections that occ…
