Scarcity of congruences for the partition function
@article{Ahlgren2020ScarcityOC, title={Scarcity of congruences for the partition function}, author={Scott Ahlgren and Olivia Beckwith and Martin Raum}, journal={arXiv: Number Theory}, year={2020} }
The arithmetic properties of the ordinary partition function $p(n)$ have been the topic of intensive study for the past century. Ramanujan proved that there are linear congruences of the form $p(\ell n+\beta)\equiv 0\pmod\ell$ for the primes $\ell=5, 7, 11$, and it is known that there are no others of this form. On the other hand, for every prime $\ell\geq 5$ there are infinitely many examples of congruences of the form $p(\ell Q^m n+\beta)\equiv 0\pmod\ell$ where $Q\geq 5$ is prime and $m\geq…
