Abstract:
In this paper we investigate multinormed $W^{\ast }$-algebras in terms of the central topologies of $W^{\ast }$-algebras. The main result asserts that each multinormed $W^{\ast }$-algebra can be realized as a local von Neumann algebra on a certain domain in a Hilbert space. Moreover, it admits the predual (unique up to an isometry), which is the $\ell _{1}$-normed space. In the normed case the assertion is reduced to the known Sakai theorem.References
