Abstract

Abstract In this paper, we introduce a new condition namely, the (W.C.C) condition and give some Suzuki-type, unique, common fixed-point theorems for pairs of hybrid mappings in partial metric spaces using a partial Hausdorff metric. These results generalize and extend the several comparable results in this literature in metric and partial metric spaces.

Highlights

  • In the case of bounded delays, many authors using standard techniques [3, 10, 20, 27, 34, 37] have studied the asymptotic behavior of solutions, the asymptotic stability in equations and the existence of positive periodic solutions of delay equations

  • By means of the matrix method based on collocation points which have been given by Sezer and coworkers [2, 6, 16, 17, 21, 26, 29, 36], we develop a novel matrix technique to find the approximate solution of Eq 1 under the initial condition yðaÞ 1⁄4 k in the truncated Morgan–Voyce series form yðtÞ ffi yN ðtÞ 1⁄4

  • A new approach using the Morgan–Voyce polynomials to solve numerically the first-order nonhomogeneous differential equations with variable delays is presented in this study

Summary

Introduction

We consider nonhomogeneous differential equation with variable delays in the form [3, 5, 10, 12, 23, 30, 37, 38]. Pj ðtÞy t sj ðtÞ ð1Þ j1⁄42 under the initial condition yðaÞ 1⁄4 k, where the coefficients. Most of the mentioned type delay equations have not analytical and numerical solutions; numerical methods are required to obtain approximate solutions. For this purpose, by means of the matrix method based on collocation points which have been given by Sezer and coworkers [2, 6, 16, 17, 21, 26, 29, 36], we develop a novel matrix technique to find the approximate solution of Eq 1 under the initial condition yðaÞ 1⁄4 k in the truncated Morgan–Voyce series form yðtÞ ffi yN ðtÞ 1⁄4.
