Web27 de abr. de 2012 · In ref. 1, J. von Neumann initiates the subject of von Neumann algebras (which he refers to as “rings of operators”) and proves what is the most fundamental theorem of the subject, his celebrated “double commutant theorem.”That theorem is, in effect, an infinite-dimensional version of Schur’s lemma. The complex … Web1 de jul. de 2024 · The operations of forming the tensor product, both finite and infinite, are also defined for von Neumann algebras. A von Neumann algebra is called a factor if its centre consists of multiples of the identity. Let $ A $ be a von Neumann algebra and $ A ^ {+} $ the set of its positive operators. A weight on $ A $ is an additive mapping $ \phi ...
