Ideal decompositions of a ternary ring of operators with predual

Masayoshi Kaneda

Vol. 266 (2013), No. 2, 297–303
Abstract

We show that any TRO (ternary ring of operators) with predual can be decomposed into the direct sum of a two-sided ideal, a left ideal, and a right ideal in some von Neumann algebra using an extreme point of the unit ball of the TRO.

Keywords
extreme points, dual operator spaces, von Neumann algebras, ideals, ternary rings of operators
