Algorithm for the Numerical Solutions of Volterra Population Growth Model with Fractional Order via Haar Wavelet

by Amin Rohul,Yüzbaşi Şuayip,Gao Liping,Asif Muhammad,Khan Imran

Abstract: In this paper, a new collocation method based on the Haar wavelet is developed for the numerical solution of the fractional Volterra model (FVM) for the population growth of a species in a closed syst...

Nonlinear Partial Differential Equations Arising from Prescribed Curvature Problems

by Man Chun Leung

Abstract: We consider two prominent nonlinear partial differential equations (nonlinear PDE) linked to the prescribed curvature problems, namely, the Minkowski problem and the Kazdan-Warner/Nirenberg problem (p...

A Note on Differential Identities in Prime and Semiprime Rings

by Mohammad Shadab Khan, Mohd Arif Raza,Rehman Nadeemur

Abstract: Let R be a prime ring, I a nonzero ideal of R, d a derivation of R and m, n fixed positive integers. (i) If (d (r ○ s)(r ○ s) + (r ○ s) d (r ○ s)n - d (r ○ s))m for all r, s ϵ I, then R is ...

Some Algebraic Properties of ℓᵖ(β)

by Y. Estaremi, M. R. Jabbarzadeh

Abstract: In this paper, we consider a generalized Cauchy product ◊ on ℓp(β) and then we characterized some Banach algebra structures for ℓp(β).  Also, some classic properties of ◊-multiplic...
