Continuity condition for concave functions on convex -compact sets and its applications in quantum physics
M. E. Shirokov
A method of proving local continuity of concave functions on convex set possessing the -compactness property is presented. This method is based on a special approximation of the…
Characterization of convex -compact sets
M. E. Shirokov
The class of -compact sets can be considered as a natural extension of the class of compact metrizable subsets of locally convex spaces, to which the particular results well kno…
Generalized compactness in linear spaces and its applications
V. Yu. Protasov, M. E. Shirokov
The class of subsets of locally convex spaces called -compact sets is considered. This class contains all compact sets as well as several noncompact sets widely used in applicat…
The output entropy of quantum channels and operations
M. E. Shirokov
Continuity properties of the output entropy of positive linear maps between Banach spaces of trace class operators are investigated with the special attention to the classes of qua…
