Abstract  

In the present paper some Newton-like iteration methods are developed to enclose solutions of nonlinear operator equations of the kindF(x)=0. HereF maps a certain subset of a partially ordered vector space into another partially ordered vector space. The obtained results are proved without any special properties of the orderings by taking use of a new kind of a generalized divided difference operator, so that they even hold for nonconvex operators. Furthermore a method for constructing including starting points is presented and two examples are given.

In the present paper we give a brief review of L 1 -convergence of trigonometric series. Previous known results in this direction are improved and generalized by establishing a new condition.

Abstract  

We show that the classical monotonicity conditions can be moderated in four theorems of P. Chandra.

Abstract

Let expX be the power set of a non-empty set X. A function γ: expX→expX is said to be monotonic iff ABX implies γAγB. Császár [2] investigated relations between the monotonic functions. The purpose of the paper is to investigate some results concerning particular monotonic functions.
