A Qualitative Study of Lobachevsky’s Complex Functional Equation

2000
The purpose of this paper is to solve Lobachevsky’s functional equation for the complex function in the complex domain and to establish the connections of this equation with some classical functional equations in the same case. Using only the boundednes property on the disk D(0;r), we deduce the continuity, differentiability property.

STABILITY OF A FUNCTIONAL EQUATION IN COMPLEX BANACH SPACES

Using fixed point technique, in the present paper , we wish to examine generalization of the Hyers-Ulam-Rassias stability theorem for the functional equations f 2 x + i y + f x + 2 i y = 4 f x + i y + f x + f y 0.1 and f 2 x + i y − f i x − 2 y = − 4 f i x − y + f x − f − y 0.2 in complex Banach spaces .
