Correction to: Pseudospin Symmetry in Position-Dependent Mass Dirac-Coulomb Problem by Using Laplace Transform and Convolution Integral

In order to solve Dirac-Coulomb differential equation in the hypergeometric functions, mass distribution has been re-solved; so that, pseudospin symmetric solutions have the consistency when the derivatives are in the form Σ′+m′=0\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\Sigma '+m'=0$$\end{document}.
