Maps on the Algebras of Measurable Operators Preserving Zero and Jordan Zero-products


I. M. Juraev

2012, issue 2, Ñ. 195–200


Abstract
In this paper, we prove that a continuous linear surjection from an algebra of measurable operators onto another one preserves zero products (resp. zero Jordan products) if and only if it is a non-zero scalar multiple of a homomorphism (resp. of an Jordan homomorphism).

Keywords:
von Neumann algebras, measurable operator, topology of convergence in measure, trace, homomorphism, Jordan homomorphism
