A Hahn decomposition for linear maps

Richard Ira Loebl

Vol. 65 (1976), No. 1, 119–133
Abstract

The question is studied whether every bounded self-adjoint linear map φ between two C-algebras can be written as the difference of bounded positive linear maps. Such a decomposition is called a Hahn decomposition of φ.
