Weierstrass points on $\Gamma_0(p)$ and its application

Abstract

In this note, we study arithmetic properties for the exponents of modular forms on $\Gamma_0(p)$ for primes $p$. Our aim is to refine the result of \cite{C-D} by using the geometric property of the modular curve of $\Gamma_0(p)$.

Keywords: modular forms, one variable, congruences for modular forms
