Stability of Jensen functional equation on semigroups
A real function \(f\) defined on a semigroup \(S\) is Jensen if it satisfies the functional equation \(f(xyz)+f(xzy)+2f(x)-2f(xy)-2f(xz)=0\). In this paper, the authors investigate the Hyers-Ulam stability of the above equation and prove that each semigroup can be embedded into a semigroup such that the equation above is stable.

GENERALIZED JENSEN'S FUNCTIONAL EQUATIONS AND APPROXIMATE ALGEBRA HOMOMORPHISMS
The generalized Hyers-Ulam-Rassias stability of the functional equation \[ 2^nf\biggl({{x_1+\dots+x_{2^n}}\over{2^n}}\biggr)=\sum_{i=1}^{2^n}f(x_i)\tag{1} \] is proved in Banach modules over a~unital \(C^{\ast}\)-algebra. The Hyers-Ulam-Rassias stability of algebra homomorphisms between Banach algebras associated with the functional equation (1) is ...

The Jensen functional equation in non‐Archimedean normed spaces [PDF]
We investigate the Hyers–Ulam–Rassias stability of the Jensen functional equation in non‐Archimedean normed spaces and study its asymptotic behavior in two directions: bounded and unbounded Jensen differences. In particular, we show that a mapping f between non‐Archimedean spaces with f(0) = 0 is additive if and only if as max {‖x‖, ‖y‖} → ∞.

Estimations of f- and Rényi divergences by using a cyclic refinement of the Jensen's inequality
The Jensen's inequality plays a crucial role to obtain inequalities for divergences between probability distributions. In this paper we introduce a new functional, based on the f-divergence functional, and then we obtain some estimates for the new ...
