A Gross-Kohnen-Zagier theorem for non-split Cartan curves

Daniel Kohen, Nicolás Sirolli

Let $p$ be a prime number and let $E / Q$ be an elliptic curve of conductor $p^{2}$ and odd analytic rank. We prove that the positions of its special points arising from non-s…

An unexpected trace relation of CM points

Daniel Kohen

Let $E / Q$ be an elliptic curve of conductor $N = p^{2} M$ where $p$ is an odd prime not dividing $M$ . Let $O_{f}$ be the order of conductor $f$ (relatively prime to $N$ …
