- Abstract
- The aim of this paper is to investigate Hyers-Ulam stability of the following lattice preserving functional equation on Riesz space with fixed point method:
parallel to F(tau x boolean OR eta y) - tau F(x) boolean OR eta F(y)parallel to <= phi (tau x boolean OR eta y, tau X Lambda eta y),
where chi is a Banach lattice and phi : chi x chi -> chi is a mapping such that
phi(x,y) <= (tau eta)(alpha/2) phi (x/tau, y/eta)
for all tau, eta >= 1 and alpha is an element of [0,1/2).
