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 ...

In this paper a generalization of collectively compact operator theory in Banach spaces is developed. A feature of the new theory is that the operators involved are no longer required to be compact in ...

Cabs and operator stations on today's skid steers, compact track loaders and compact excavators are being designed to ensure operators stay both happy and productive. Growth in construction activity ...
