[M-F. Bota, A. Petrusel, G.<br />Petrusel and B. Samet, Coupled fixed point theorems for<br />single-valued operators in b-metric spaces, Fixed Point Theory<br />Appl. (2015) 2015:231]. Also, we prove that Perov-type fixed point<br />theorem in ordered generalized $b$-metric spaces is equivalent<br />with Ran-Reurings-type theorem in ordered $b$-metric spaces.http://mir.kashanu.ac.ir/article_34117_19cd984494f700f7386f297cf2421a30.pdf
