First paragraph (this article has no abstract)
In this manuscript, we prove some quadruple coincidence and common fixed point theorems for F : X4 → X and g : X → X satisfying generalized contractions in partially ordered metric spaces. Our results unify, generalize and complement various known results from the current literature. Also, an application to matrix equations is given.
