Abstract

We study connections between the (Formula presented.) -differentiability and the (Formula presented.) -differentiability of Sobolev functions. We prove that (Formula presented.) -differentiability implies the (Formula presented.) -differentiability, but the opposite implication is not valid. The notion of approximate differentiability is discussed as well. In addition, we consider the (Formula presented.) -differentiability of Sobolev functions (Formula presented.) -almost everywhere.
