We consider finite graphs whose vertexes are supersingular elliptic curves, possibly with level structure, and edges are isogenies. They can be applied to the study of modular forms …

Let ℓ and p be two distinct prime numbers. We study ℓ-isogeny graphs of ordinary elliptic curves defined over a finite field of characteristic p, together with a level structure. Firstly, we …

Let $ p> 3$ be a prime and $ E $ be a supersingular elliptic curve defined over $\mathbb {F} _ {p^ 2} $. Let $ c $ be a prime with $ c< 3p/16$ and $ G $ be a subgroup of $ E [c] $ of order …
