Rethinking Number Theory

Given a rational elliptic curve, one can use Tate's algorithm to determine local data of the elliptic curve at each prime. This includes the Néron type, conductor, and Tamagawa number. It is well known that the isogenous elliptic curves have the same conductor. For an elliptic curve with non-trivial torsion, we investigate how the Néron type and Tamagawa number change along it's isogeny graph.
