Abstract
The purpose of this paper is to describe some recent results regarding the arithmetic properties of Weierstrass points on modular curves X 0 (p) for primes p. We begin with some generalities; most of these can be found, for example, in the book of Farkas and Kra [F-K]. Suppose that X is a compact Riemann surface of genus g ≥2. If γ is a positive integer, then let H r (X) denote the space of holomorphic r-differentials on X. Each H r (X) is a finite-dimensional vector space over ℂ; we denote its dimension by d r (X). A point Q ∈ X is called an r-Weierstrass point if there exists a non-zero differential w ∈ H r (X) such that $${\operatorname{ord} _{Q\omega }} \geqslant {d_r}\left( X \right)$$ KeywordsModular FormCusp FormCompact Riemann SurfaceWeierstrass PointModular CurfThese keywords were added by machine and not by the authors.
