Letter sent October 21, 2023 to Harvard Mathematics, with copies to the office of the president and GSAS
Colleagues,
As Harvard is aligning itself with a monstrosity, I am looking into the process of obtaining a PhD from an Israeli university and relinquishing my Harvard PhD. I trust that members of my PhD committee at Harvard will fully cooperate with the process. I am asking that you look into the process and inform me of how to go about doing it.
Sincerely
- Dan Abramovich
