Miscellanea About the Stability of Functional Equations,The interesting details about the stability, the superstability, the inverse stability, the absolute stability and the stability in a class for a functional equation, for a system, and the alternation of functional equations, about the approximation of approximation and about the nearness of two approximations are given.

Ulam Stability of Zero Point Equations,In this paper, we will study different kind of Ulam stability concepts for the zero point equation. Our approach is based on weakly Picard operator theory related to fixed point and coincidence point equations.

Semi-Inner Products and Parapreseminorms on Groups and a Generalization of a Theorem of Maksa and VBy using inner products and paraprenorms on groups, we prove a natural generalization of a basic theorem of Gyula Maksa and Peter Volkmann on additive functions.
