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

I. M. Juraev

National University of Uzbekistan named after M. Ulugbek, Tashkent

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).

Key words: von Neumann algebras, measurable operator, topology of convergence in measure, trace, homomorphism, Jordan homomorphism.
