In this work, the formula of fuzzy derivative of the fifth order and fuzzy Laplace transform for the fuzzy derivative of the fifth order are found by using generalized H-differentiability, which can be applied in finding solutions for fuzzy initial value problems of the fifth order.

The present study is concerned with construct two new semidynamical systems which are generated by two partial differential equations of Lasota type. In addition, this study discusses the asymptotic properties: Strong stability, exponential stability, periodic points, the density of periodic points, transitivity and chaos in two spaces: Lp space and bL p space.

In this paper, we use the Lambert W function to introduce a solution for fourth order and then nth- order dynamical systems of retarded type. As well as, we discuss analytical stability through illustrative examples.

The main aim of this paper is to find the general formula to the fuzzy derivative of the n -th order and the general formula for fuzzy Laplace transforms to the fuzzy derivative of the n -th order by using generalized H-differentiabilit

The main aim in this paper is to use all the possible arrangements of objects such that

In this paper, we find formulas of fuzzy Sumudu transform for the fuzzy derivatives of orders three and four. Then, we generalize these formulas to the fuzzy nth- order derivative by using strongly generalized H-differentiability concepts. A fuzzy initial value problem FIVP of order four is provided.
