| Research Abstract |
In this study, a unified approach to addressing a wide class of mathematical models that include ordinary differential equations, partial differential equations, and difference differential equations has been introduced using the semigroup theory. The stabilization method for such a class of systems has been established using the properties of a non-negative semigroup. However, the applicability of the method is restricted to a class of systems that satisfy the non-negativity assumption. To remove such a restrictive assumption that system coefficients are non-negative, a variable transformation method has been developed for stabilizing a system whose coefficients are not necessarily non-negative.
