In this paper, we define timelike curves in R4 2 and characterize such curves in terms of Frenet frame. Also, we examine the timelike helices of R4 2, taking into account their curvatures. In addition, we study timelike slant helices, timelike B1-slant helices …

In this paper, we propose a non-autonomous reaction–diffusion SIR infectious disease model with nonlinear incidence, taking fully into account the effects of periodic environmental factors as well as population dynamics on disease …
H Sweis, N Shawagfeh, OA Arqub – Results in Physics, 2022
In the present work, we consider a class of fractional delay differential equations of order ρ with Atangana-Baleanu fractional derivatives in the Caputo sense. We convert our fractional delay problem to Volterra integral equation and used them to …

Chaotic systems arise everywhere in control theory and nonlinear vibration. This paper uses a high-precision numerical approach for capturing chaotic attractors of the fractional EI Ni ñ o chaotic systems. The numerical results indicate that some of …
A Das, B Hazarika, BC Deuri – Fractional Calculus and Applied Analysis, 2022
In this article, the existence of the solution of infinite system of fractional hybrid differential equations with initial conditions by reducing them to integral equations in the space C (I, m (θ) β) is discussed based on Darbo fixed point theorem. In the end …

With the rapid development of online media in recent years, rumors have also proliferated and spread. If they are not effectively managed, they will cause great harm to society. So, how to stop the spread of rumors has become a hot topic that …
T ABDELJAWAD, N MLAIKI, MS ABDO – Fractals, 2022
In this paper, we introduce a new class of fractional impulsive systems of functions with respect to another function in which the order of the fractional derivative and the kernel function is associated with the impulses. We derive the solution …
AA Hyder, H Budak, AA Almoneef – Fractal and Fractional, 2022
In this study, new midpoint-type inequalities are given through recently generalized Riemann–Liouville fractional integrals. Foremost, we present an identity for a class of differentiable functions including the proposed fractional integrals. Then, several …
