In this paper, we dene the notion of a coupled coincidence fixed point and prove a coupled coincidence fixed<br />point theorem in dislocated quasi b-metric space. In order to validate our main result and its corollaries an<br />example is given

The present paper proposes a new monotone iteration principle for the existence as well as approximations<br />of the tripled solutions for a tripled periodic boundary value problem of second order ordinary nonlinear<br />differential equations. An algorithm for the tripled solutions is developed and it is shown that the sequences<br />of successive approximations defined in a certain way converge monotonically to the tripled solutions of the<br />related differential equations under some suitable hybrid conditions. A numerical example is also indicated<br />to illustrate the abstract theory developed in the paper.

In this paper a nonlinear inverse heat conduction problem in one dimensional space is considered. This<br />inverse problem reformulate as an auxiliary inverse problem. Ill-posedness is identified as one of the main<br />characteristics of the inverse problems. So, a numerical algorithm based on the combination of discrete<br />mollification and space marching method is applied to conquer ill-posedness of the auxiliary inverse problem.<br />Moreover, a proof of stability and convergence of the aforementioned algorithm is provided. Eventually, the<br />efficiency of this method is illustrated by a numerical example.

The aim of this paper is to introduce a new type of contraction called Θ-G-contraction on a metric<br />space endowed with a graph and establish some new fixed point theorems. Some examples are presented<br />to support the results proved herein. Our results unify, generalize and extend various results related with<br />G-contraction for a directed graph G
