Generalized Quasilinearization versus Newton's Method for Convex-Concave Functions

  •  Cesar Martinez-Garza    


In this paper we use the Method of Generalized Quasilinearization to obtain monotone Newton-like comparative schemes to solve the equation F(x)=0, where  F(x) Î C[W,R].  Here, F(x) admits the decomposition F(x)=f(x)+g(x),  where f(x) and g(x)  are convex and concave functions in W,  respectively.  The monotone sequences of iterates are shown to converge quadratically.  Four cases are explored in this manuscript.
