Abstract: In this paper we give the necessary and sufficient conditions for the embedding of an anisotropic Banach space valued Musielak-Orlicz space into another anisotropic Banach space valued Musielak-Orlicz space, and the necessary and sufficient conditions for a subset of an anisotropic Banach space valued Musielak-Orlicz space to be relatively compact, and characterize the uniform convexity of anisotropic Banach space valued Musielak-Orlicz space.

Key words: Banach space valued Musielak-Orlicz space, Embeddedness, Compactness, Uniform convexity
