An abstract algebraic-topological approach to the notions of a first and second dual space. III. (English) Zbl 1361.46004
Summary: Here we continue to develop a concept, that generalizes the idea of the second dual space of a normed vector space in a fairly general way. As in the prequel, the main tool is to recognize the “first dual” as a means to the end of the second dual. Especially, we will easily prove here some essential statements on embeddings of noncommutative \(C^{*}\)-algebras in their second dual, whose analogues are known in the commutative setting.
