Abstract :
In this paper, we first discuss properties of the cone in normed product spaces. As applications, we then derive some coupled best approximation and coupled coincidence best approximation point results for discontinuous operators in partially ordered Banach spaces. Some of our results generalize those obtained in earlier work.
