Modified Newton method to determine multiple zeros of nonlinear equations
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2016, Vol 11, Issue 10
Abstract
New one-point iterative method for solving nonlinear equations is constructed. It is proved that the new method has the convergence order of three. Per iteration the new method requires two evaluations of the function. Kung and Traub conjectured that the multipoint iteration methods, without memory based on n evaluations, could achieve maximum convergence order2n-1 but, the new method produces convergence order of three, which is better than expected maximum convergence order of two. Hence, we demonstrate that the conjecture fails for a particular set of nonlinear equations. Numerical comparisons are included to demonstrate exceptional convergence speed of the proposed method using only a few function evaluations.

Commutativity of Addition in Prime Near-Rings with Right (θ,θ)-3-Derivations
Let N be a near-ring and is a mapping on N . In this paper we introduce the notion of right ()-3-derivation in near-ring N. Also, we investigate the commutativity of addition of prime near-rings satisfying certain...
On Full k-ideals of a Ternary Semiring
In this paper, we generalize the concept of the full -ideals of a semiring to ternary semiring and prove that the set of zeroids annihilator of a right ternary semimodule, and the Jacobson radical of a ternary semiring a...
An infinite plate with a curvilinear hole having three poles with complex parameters
This paper covered the study of the boundary value problem for isotropic homogeneous perforated infinite elastic media. For this, we considered the problem of a thin infinite plate of specific thickness with a curvilinea...
Dynamics of certain anti-competitive systems of rational difference equations in the plane
In this paper, we consider a system of rational difference equations and we will prove that the unique positive equilibrium point of this system is globally asymptotically stable. We also determine the rate of convergenc...
Some convergence theorems for order-Mcshane equi-integral in Riesz space
In this paper we prove some convergence theorems of order-Macshane equi -integrals on Banach lattice and arrive same result in L-space as on Mcshane norm-integrals.
