The stability of differential-difference systems with linearly increasing delay. II. Systems with additive right side

Vestnik of Saint Petersburg University Applied Mathematics Computer Science Control Processes, 2023
The article considers an uncontrolled system of differential-difference equations with a homogeneous additive right side and linearly increasing delay. Sufficient conditions for asymptotic stability are known for a number of special cases of such systems.

Reduction of quad-equations consistent around a cuboctahedron I: Additive case [PDF]

Proceedings of the American Mathematical Society, Series B, 2020
In this paper, we consider a reduction of a new system of partial difference equations, which was obtained in our previous paper (Joshi and Nakazono, arXiv:1906.06650) and shown to be consistent around a cuboctahedron. We show that this system reduces to

Intuitionistic fuzzy stability results of additive functional equation by two different approaches

Journal of Physics: Conference Series, 2021
Abstract In this current work, we examine the Hyers-Ulam(H-U) stability results for a finite variable additive functional equation (Ref.[6]) in Intuitionistic Fuzzy Normed space(IFN-space) is discussed by means of direct and fixed point methods.
