Images of isogeny classes on modular elliptic curves

Pages: 649 – 651



Florian Breuer (University of Stellenbosch)


Let $K$ be a number field and $E/K$ a modular elliptic curve, with modular parametrization $\pi : X_0(N) \longrightarrow E$ defined over $K$. The purpose of this note is to study the images in $E$ of classes of isogenous points in $X_0(N)$.
