Abstract

The main goal of this paper is to introduce and explore an appropriate notion of weakly Rickart JB^*-triples. We introduce weakly order Rickart JB^*-triples, and we show that a C^*-algebra AA is a weakly (order) Rickart JB^*-triple precisely when it is a weakly Rickart C^*-algebra. We also prove that the Peirce-2 subspace associated with a tripotent in a weakly order Rickart JB^*-triple is a Rickart JB^*-algebra in the sense of Ayupov and Arzikulov. By extending a classical property of Rickart C^*-algebras, we prove that every weakly order Rickart JB^*-triple is generated by its tripotents.
