Potential good reduction

“For elliptic curves, potential good reduction is equivalent to the j-invariant being an algebraic integer” [1].

Good reduction

“Definition of good reduction (asked Mar 20, 2018 by 57Jimmy)” [2].

Good question, but no good answers as yet, six years later.

Bad reduction

“bad reduction for elliptic curves (asked Feb 27, 2010 by schur)” [3].

A “nice try,” apparently. but still no good answers, 14 years later.
