The Newtonian limit on cosmological scales [PDF]

open access: yes, 2015
We establish the existence of a wide class of inhomogeneous relativistic solutions to the Einstein-Euler equations that are well approximated on cosmological scales by solutions of Newtonian gravity.

On the multiplicative Legendre equation

open access: yesJournal of Taibah University for Science, 2022
When exponentials are employed to model procedures and efficacies appearing in real life, an additive derivative of this type of function does not exist.

Determination of the Köthe-Toeplitz Duals over the Non-Newtonian Complex Field

open access: yesThe Scientific World Journal, 2014
The important point to note is that the non-Newtonian calculus is a self-contained system independent of any other system of calculus. Therefore the reader may be surprised to learn that there is a uniform relationship between the corresponding operators

Certain Spaces of Functions over the Field of Non-Newtonian Complex Numbers

open access: yesAbstract and Applied Analysis, 2014
This paper is devoted to investigate some characteristic features of complex numbers and functions in terms of non-Newtonian calculus. Following Grossman and Katz, (Non-Newtonian Calculus, Lee Press, Piegon Cove, Massachusetts, 1972), we construct the ...

The Fractal Tapestry of Life: III Multifractals Entail the Fractional Calculus

open access: yesFractal and Fractional, 2022
This is the third essay advocating the use the (non-integer) fractional calculus (FC) to capture the dynamics of complex networks in the twilight of the Newtonian era. Herein, the focus is on drawing a distinction between networks described by monfractal
