Abstract In this thesis we introduce the concept of monotone point to set vector fieldin a Riemannian manifold and give a characterization that make clear in thisdefinition the occult geometric meaning We will show that sub differentialoperator of a Riemannian convex function is a monotone point to set vectorfield The concept of directional derivative plays an Important role in theproof of the result above We study some of its properties in particular weobtain the chain rule which is fundamental in our work
