Benjamin Bedert
In 1970, Erdős and Sárközy wrote a joint paper studying sequences of integers having what they called property P, meaning that no divides the sum of two large…

Twisting moduli for GL(2)
Benjamin Bedert, George Cooper, Thomas Oliver +1
We prove various converse theorems for automorphic forms on Γ_0(N), each assuming fewer twisted functional equations than the last. We show that no twisting at all is needed for ho…
