Abstract
Rubio’s mappings between the Thomson and Darboux cubics are generalized for pairs of cubics of the form p α(β 2−γ 2)+ q β(γ 2−α 2)+ r γ(α 2 − β 2) = 0, where p, r, q, α, β, γ are functions of a triple (a, b, c) of variables or indeterminates. Methods include symbolic substitutions, such as (a, b, c) → (bc, ca, ab). Connections between the generalized Rubio mappings with generalized Cundy–Parry mappings are described.
