Pseudo-Derivative and Pseudo-Integral of Fractional Order
Journal of Mathematical Extension, 2014 Integral and differential of fractional order are important notion that is often used in dealing with Frechet geometry. Based on pseudo-operations given by monotone and continuous function g, we study pseudo-derivative and pseudo-integral of ...

Relativistic covariance and nonlinear quantum mechanics: Tomonaga-Schwinger analysis
Physics Letters BWe use the Tomonaga–Schwinger (TS) formulation of quantum field theory to determine when state-dependent additions to the local Hamiltonian density (i.e., modifications to linear Schrödinger evolution) violate relativistic covariance.

Local Convergence Analysis of an Efficient Fourth Order Weighted-Newton Method under Weak Conditions
Annals of the West University of Timisoara: Mathematics and Computer Science, 2018 Local convergence analysis of a fourth order method considered by Sharma et. al in [19] for solving systems of nonlinear equations. Using conditions on derivatives upto the order five, they proved that the method is of order four.

The approximation of the solutions of equations using approximant sequences
Journal of Numerical Analysis and Approximation Theory, 2003 We intend to characterize the convergence of a certain sequence that belongs to a subset of a Banach space towards the solution of an equation obtained by the annulment of a nonlinear mapping that is defined on this subset and that takes values in ...

An Improved Convergence Analysis of a Multi-Step Method with High-Efficiency Indices
AlgorithmsA multi-step method introduced by Raziyeh and Masoud for solving nonlinear systems with convergence order five has been considered in this paper. The convergence of the method was studied using Taylor series expansion, which requires the function to be ...

On the range of the derivative of a smooth mapping between Banach spaces
Abstract and Applied Analysis, 2005 We survey recent results on the structure of the range of the derivative of a smooth mapping f between two Banach spaces X and Y. We recall some necessary conditions and some sufficient conditions on a subset A of ℒ(X,Y) for the existence of a Fréchet ...

Stability Results for an Age-Structured SIS Epidemic Model with Vector Population
Journal of Applied Mathematics, 2015 We formulate an age-structured SIS epidemic model with periodic parameters, which includes host population and vector population. The host population is described by two partial differential equations, and the vector population is described by a single ...
