We study the quasi-weakly compact operators between normed spaces, which are described in terms of their first and second conjugates. Using a result on factorisation of an arbitrary linear operator ...
Abstract.We give a survey of the known results concerning the sets 𝑐₀(Λ), 𝑐(Λ) and 𝑐∞(Λ) including their basic topological properties, their first and second dual spaces, and the characterizations ...
