Wu, Hsien-Chung Coincidence point and common fixed point theorems in the product spaces of quasi-ordered metric spaces. (English) Zbl 1437.54072 J. Nonlinear Var. Anal. 1, No. 2, 175-199 (2017). Summary: The main aim of this paper is to study and establish some new coincidence point and common fixed point theorems in the product spaces of complete quasi-ordered metric spaces. The fixed point theorems in the product spaces will be the special case of coincidence point theorems in the product spaces. We also show that the concept of fixed point theorems in the product spaces extends the concept of coupled fixed point theorems.
