On certain cusp forms on a definite quaternion

In this note, extracted from the above preprint, we give a detailed proof of a Deuring-type correspondence between supersingular elliptic curves (with some additional structure) in characteristic p, and a double coset space arising from the multiplicative group of the definite quaternion with discriminant p
