Martínez-Garza","doi":"10.5539/JMR.V2N3P63","DOIUrl":"https://doi.org/10.5539/JMR.V2N3P63","url":null,"abstract":"In this paper we use the Method of Generalized Quasilinearization to obtain Newton-like comparative schemes to solve the equation $f(x)=0$, which has an isolated zero, $x=r$ in $[a_0,b_0]subset Omega$, where $f(x) in C[Omega,mathbb{R}]$. Two sets of results are presented. In the first cases $f(x)$ is neither concave nor convex, but by the addition of the convex function $phi(x)$, convexity properties are then used on $F(x)=f(x)+phi(x)=0$ to show that an iterative scheme based on Generalized Quasilinearization generates two monotone sequences ${a_n}$ and ${b_n}$ that converge quadratically to $r$, the isolated zero of $f(x)=0$. The first set of results are then extended to the case where $f(x)$ admits the decomposition $f(x)=F(x)+G(x)$, where $F(x)$ and $G(x)$ are not naturally convex and concave, but are forced by adding the functions $Phi(x)$ and $Psi(x)$ with $Phi_{xx}(x)>0$ and $Psi_{xx}(x)leq 0$ in $Omega$. The existence of monotone sequences that converge quadratically to the isolated root of $f(x)=0$ in $[a_0,b_0]subsetOmega$ is shown via iterative schemes relevant to Generalized Quasilinearization.","PeriodicalId":38616,"journal":{"name":"Nonlinear Studies","volume":"17 1","pages":"267-277"},"PeriodicalIF":0.0,"publicationDate":"2010-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5539/JMR.V2N3P63","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70799255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
