Shehu Integral Transform and Hyers-Ulam Stability of nth order Linear Differential Equations

open access: yesScientific African, 2022
In this paper, we establish the Shehu transform expression for homogeneous and non-homogeneous linear differential equations. With the help of this new integral transform, we solve higher order linear differential equations in the Shehu sense.

Extensions of Gronwall-Bellman type integral inequalities with two independent variables

open access: yesOpen Mathematics, 2022
In this paper, we establish several kinds of integral inequalities in two independent variables, which improve well-known versions of Gronwall-Bellman inequalities and extend them to fractional integral form.

Criteria of Existence for a q Fractional p-Laplacian Boundary Value Problem

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
This paper is devoted to establishing some criteria for the existence of non-trivial solutions for a class of fractional q-difference equations involving the p-Laplace operator, which is nowadays known as Lyapunov's inequality. The method employed for it

Perturbation of the one-dimensional time-independent Schrödinger equation with a rectangular potential barrier

open access: yesOpen Mathematics, 2020
In Applied Mathematics Letters 74 (2017), 147–153, the Hyers-Ulam stability of the one-dimensional time-independent Schrödinger equation was investigated when the relevant system has a potential well of finite depth. As a continuous work,

TIME-VARYING LYAPUNOV FUNCTIONS AND LYAPUNOV STABILITY OF NONAUTONOMOUS FRACTIONAL ORDER SYSTEMS

open access: yesInternational Journal of Apllied Mathematics, 2019
We present a new inequality which involves the Caputo fractional derivative of the product of two continuously differentiable functions, and establish its various properties. The inequality and its properties enable us to construct potential time-varying

Oscillation criteria for nonlinear inhomogeneous hyperbolic equations with distributed deviating arguments

open access: yesInternational Journal of Stochastic Analysis, Volume 9, Issue 1, Page 21-31, 1996., 1995
This paper investigates the oscillatory properties of solutions of nonlinear inhomogeneous hyperbolic equations with distributed deviating arguments subject to two different boundary conditions. Several oscillation criteria are establishing employing Green′s Theorem and certain differential inequalities. An example is also given.

Differential inequalities for hysteresis systems

open access: yesInternational Journal of Stochastic Analysis, Volume 9, Issue 4, Page 459-468, 1996., 1996
The theory of differential inequalities is extended to functional‐differential equations with hysteresis nonlinearities. A key feature is the existence of a semiorder of the state space of nonlinearity and a special monotonicity of the righthand side of differential inequality. This article is dedicated to the memory of Roland L. Dobrushin.

Lyapunov-type inequalities for a fractional differential equation with mixed boundary conditions

open access: yes, 2015
Lyapunov-type inequalities are established for a fractional differential equation under mixed boundary conditions. Using such inequalities, we obtain intervals where certain MittagLeffler functions have no real zeros.

Further generalization of generalized quasilinearization method

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 4, Page 545-552, 1994., 1994
The question whether it is possible to develop monotone sequences that converge to the solution quadratically when the function involved in the initial value problem admits a decomposition into a sum of two functions, is answered positively. This extends the method of generalized quasilinearization to a large class.
