| Research Abstract |
Our aim is to study Musielak-Orlicz Sobolev spaces on metric measure spaces. We consider a Hajlasz type condition and a Newtonian type condition. We prove that Lipschitz continuous functions are dense as well as other basic properties. We study the relationship between these spaces, and discuss Lebesgue point theorem in these spaces. We also deal with the boundedness of the Hardy-Littlewood maximal operator on Musielak-Orlicz spaces. As an application of the boundedness of the Hardy-Littlewood maximal operator, we establish a generalization of Sobolev's inequality for Sobolev functions in Musielak-Orlicz-Hajlasz spaces.
