In this paper, we study four types of generalized open sets: Pre-I-open sets, Semi-I-open sets, α-I-open sets, and b-I-open sets, in ideal topological spaces and define the regular and normal spaces for these generalized open sets. We establish some of their properties and compare these regular and normal spaces

The problem of constructing a satisfactory theory of fuzzy metric spaces has been investigated by several researchers from different point of view. The concept of fuzzy sets was introduced by Zadeh. Following fuzzy metric ...
Variable time-stepping algorithms are often used to solve the dynamical systems, defined by autonomous initial value ordinary differential equations =f, y(0)=y0 m, where f : is a Lipschitz continuous function. Standard ...

We consider a phase space stability error control for numerical simulation of dynamical systems. Tony Humphries and Vigneswaran, R., in “Phase space stability error control with variable time-stepping Runge-Kutta methods ...
