Abstract

The stability of the functional equation F(x + y) - G(x - y) = 2H(x) K(y) over the domain of an abelian group G and the range of the complex field, with either the function H or K being bounded, is investigated. This complements an earlier similar work where such function boundedness was not treated. © 2010 American Institute of Physics.
