摘要：We are concerned here with Sobolev-type space of functions valued in Banach space or in metric space. We review two ways of defining Sobolev maps valued in metric space: Reshetnyak’s approach vs deffinition via postcomposition with the Kuratowski embedding. In particular, we show that Sobolev map with values in dual-to-separable Banach space can be described in terms of classical weak derivatives in a weak* sense.
