We show that if p is a prime, then all elliptic curves defined over the cyclotomic Z_p extension of Q are modular.

We determine all modular curves $X_0(N)$ with infinitely many quartic points. To do this, we define a pairing that induces a quadratic form representing all possible degrees of a rational morphism from $X_0(N)$ to a positive rank elliptic…
