Functions having the Darboux property and satisfying some functional equation Eliza Jabłońska (2009) Colloquium Mathematicae Let X be a real linear topological space. We characterize solutions f:X → ℝ and M:ℝ → ℝ of the equation f(x+M(f(x))y) = f(x)f(y) under the assumption that f and M have the Darboux property.
