Theory of Operator Algebras I

Mathematics for infinite dimensional objects is becoming more and more important today both in theory and application. Rings of operators, renamed von Neumann algebras by J. Dixmier, were first introduced by J. von Neumann fifty years ago, 1929, in [254] with his grand aim of giving a sound founda- tion to mathematical sciences of infinite nature. J. von Neumann and his collaborator F. J.
