Generalized Hyers-Ulam Stability of a System of Bi-Reciprocal Functional Equations

K. Ravi, Senthil Kumar


In this paper, we nd the generalized Hyers-Ulam stability of the
system of bi-reciprocal functional equations
r(x + u, y) = r(x, y)r(u, y)/[r(x, y) + r(u, y)];
r(x, y + v) = r(x, y)r(x, v)/[r(x, y) + r(x, v)]
in Frechet spaces.
