![]() Free Download Positive Solutions of Differential, Difference and Integral Equations by Ravi P. Agarwal , Donal O'Regan , Patricia J. Y. Wong English | PDF | 1999 | 425 Pages | ISBN : 0792355105 | 23.2 MB In analysing nonlinear phenomena many mathematical models give rise to problems for which only nonnegative solutions make sense. In the last few years this discipline has grown dramatically. This state-of-the-art volume offers the authors' recent work, reflecting some of the major advances in the field as well as the diversity of the subject. ![]() Free Download Positive Linear Maps of Operator Algebras by Erling Størmer English | PDF (True) | 2013 | 135 Pages | ISBN : 3642343686 | 1.4 MB This volume, setting out the theory of positive maps as it stands today, reflects the rapid growth in this area of mathematics since it was recognized in the 1990s that these applications of C*-algebras are crucial to the study of entanglement in quantum theory. The author, a leading authority on the subject, sets out numerous results previously unpublished in book form. In addition to outlining the properties and structures of positive linear maps of operator algebras into the bounded operators on a Hilbert space, he guides readers through proofs of the Stinespring theorem and its applications to inequalities for positive maps.
