Stability of lattice functional equation in UCBF-algebra

Abstract

The main aim of this research is to investigate the stability of a functional equation that maintains the lattice structure in a uniformly complete unital Banach $f$-algebra. Through this inquiry, we can shed light on the behavior of this equation and its relationship with the algebraic properties of a Banach space. This research has both theoretical and practical implications. It contributes to the foundations of functional analysis, lattice theory, operator theory, approximation theory, and various applied mathematical disciplines. The findings from this research can have implications in diverse fields ranging from mathematics and physics to engineering and computer science, offering valuable insights and potential applications.
