Stability of the Cauchy-Jensen Functional Equation in C∗-Algebras: A Fixed Point Approach

Fixed Point Theory and Applications, 2008
we prove the Hyers-Ulam-Rassias stability of C∗-algebra homomorphisms and of generalized derivations on C∗-algebras for the following Cauchy-Jensen functional equation 2f((x+y)/2+z)=f(x)+f(y)+2f(z), which was introduced and investigated by Baak

On the Stability of a Cubic Functional Equation in Random Normed Spaces

Journal of Mathematical Extension, 2009
The concept of Hyers-Ulam-Rassias stability has been originated from a stability theorem due to Th. M. Rassias. Recently, the Hyers-Ulam-Rassias stability of the functional equation f(x + 2y) + f(x − 2y) = 2f(x) − f(2x) + 4n f(x + y) + f(x − y) o ,

Existence, uniqueness and stability analysis for a f $\mathfrak{f}$ -Caputo generalized proportional fractional boundary problem with distinct generalized integral conditions

Boundary Value Problems
This paper aims to examine the existence, uniqueness, and stability properties of a novel category of f $\mathfrak{f}$ -Caputo generalized proportional differential equations characterized by two distinct fractional orders. We explore and discuss various
