A generalized Hyers Ulam stability of a Pexiderized logarithmic functional equation in restricted domains Jae-Young Chung Department of Mathematics Kunsan National University Kunsan 573-701 Republic of Korea Email address jychung@ Abstract Let R- and B be the set of positive real numbers and a Banach space respectively f g h R- B and à R R be a nonnegative function of some special forms. Generalizing the stability theorem for a Jensen-type logarithmic functional equation we prove the Hyers Ulam stability of the Pexiderized logarithmic functional inequality llf xy - g x - h y ll à x y in restricted domains of the form
