Providing some context: i want to create a class to operate on isogeny graphs of elliptic curves. So it should have the j-invariants (integers modulo p) as nodes and the existence of l-isogenies as edges.
To compute the edges i need to do some calculations on GF(p) and some others on the ring PolynomialRing(GF(p), ['X', 'Y']).
How do i make sure the operations happen on their specific rings and don't change the field outside of the class?
