Abstract

In this study, concepts of variable-order β(μ)-derivative and β(μ)-integral are presented. It is proven properties such as differentiability, continuity, linearity, commutative, associative etc. of variable-order β(μ)-derivative. To prove that the generalized definition of the β(μ)-derivative is effective, applicable and useful, it is considered a differential equation of variable-order. It is demonstrated solvability of the Rosenau-Hynam equation with variable-order β(μ)-derivative as semi-analytical with the modified variational iteration method. It is examined the comparison of semi-analytical solutions with the exact solution and their oscillation. It is commented on the usefulness, effectiveness and reliability of modified variational iteration method for relevant equations. It is enriched semi-analytical solutions of the Rosenau-Hynam equation with variable β(μ)-orders such as trigonometric, exponential and hyperbolic functions. The results are interpreted with the help of tables and figures.
