Benjamin Antieau, Daniel Krashen, Matthew Ward
In the first part of our paper, we show that there exist non-isomorphic derived equivalent genus curves, and correspondingly there exist non-isomorphic moduli spaces of stable…

Matthew Ward
We extend the sum-of-divisors function to the complex plane via the Gaussian integers. Then we prove a modified form of Euler's classification of odd perfect numbers.
