Bhaskar-Lakshmikantham type results for monotone mappings in partially ordered metric spaces

In this paper, coupled fixed point results of Bhaskar-Lakshmikantham type [T. Gnana Bhaskar, V. Lakshmikantham, Fixed point theorems in partially ordered metric spaces and applications, Nonlinear Analysis ۶۵ (۲۰۰۶) ۱۳۷۹-۱۳۹۳] are extend, generalized, unify and improved by using monotone mappings instead mappings with mixed monotone property. Also, an example is given to support these improvements.
