👉 In mathematics, an isogeny or isogonic relation between two algebraic structures can be defined as a map that preserves certain properties of the underlying structures. Specifically, if A and B are algebraic structures, then an isogeny f from A to B is a homomorphism such that for all elements a in A and b in B: 1. (a) f(a) = f(b). 2. (b) If x ∈ A and y ∈ B, then f
