Supersingular isogeny graphs and Hecke modules with level structure

Leonardo ColÃ², David Kohel

We study supersingular isogeny graphs with level structure and their associated Galois representations.

Weber modular curves and modular isogenies

Leonardo ColÃ², David Kohel

We study the modular curves defined by Weber functions, and associated modular polynomials, action of $SL_{2} (Z)$ , and parametrizations of elliptic curves with a vi…

From Orientations to $ℓ$ -adic Period Vectors

Leonardo ColÃ²

We propose a bridge between oriented supersingular elliptic curves and the arithmetic of modular curves. To an $O$ -oriented supersingular curve, we attach a class in the…
