👉 The term "isogenetic" in mathematics refers to a property that two objects (such as points in geometry or curves in algebraic geometry) have in common, but are not identical. In other words, it relates to properties of an object that are independent of its dimensions and coordinates. In the context of isogeny theory, isogenies play a crucial role because they relate two mathematical structures by means of their underlying geometrical or algebraic transformations. Isogeny theory studies such transformations
