In this paper: In this paper we give the necessary and sufficient conditions for bi-null curves in ℝ63 to be osculating, normal or rectifying curves in terms of their curvature functions.

In this paper: In this paper, we investigate inextensible flows of curves according to alternative moving frame in Euclidean space 𝔼3. Using the Prenet frame of the given curve, we present partial differential equat...

In this paper: This paper concerns the existence of solution to an initial fractional problem of arbitrary order. The main tools for this study are the lower ad upper solutions method and Schauder’s fixed point Theo...

In this paper: It is known that electric and magnetic parts of the Weyl tensor in General Relativity are analogous to that occur in the theory of electromagnetism. On the other hand, Newman-Penrose formalism provide...
In this paper: The purpose of the present article is to study and characterize several types of symmetries of generalized Robertson-Walker spacetimes. Conformal vector fields, curvature and Ricci collineations are s...

In this paper: In this paper, we focus attention on extending the topological conjugacy of adding machine maps and minimal systems to iterated function systems. We provide necessary and sufficient conditions for an...

In this paper: A locally rotationally symmetric (LRS) Bianchi type-II spacetime is considered in the presence of dark matter and anisotropic modified holographic Ricci dark energy in the scalar-tensor theory of Saez...
