Let (S, +) be a commutative semigroup, c : S S be an endomorphism with c2 = id and let K be a field of characteristic different from 2. Inspired by the problem of strong alienation of the Jensen equation and the exponential Cauchy equation, we study the solutions f, g : S K of the functional equation f (x + y) + f (x + c(y)) + g(x + y) = 2f (x) + g(x)g(y) for x, y e S. We also consider an analogous problem for the Jensen and the d'Alembert equations as well as for the d'Alembert and the exponential Cauchy equations.(original abstract)
