A FIXED POINT APPROACH TO THE STABILITY OF QUADRATIC (ƿ1, ƿ2)-FUNCTIONAL INEQUALITIES.

In this paper, we introduce and solve the following quadratic (ƿ1, ƿ2)-functional inequalities... where ƿ1 and ƿ2 are fixed nonzero complex numbers with... where ƿ1 and ƿ2 are fixed nonzero complex numbers with... Using the fixed point method, we prove the Hyers-Ulam stability of the quadratic (ƿ1; ƿ2)- functional inequalities (0.1) and (0.2) in complex Banach spaces. [ABSTRACT FROM AUTHOR]
