Abstract

Let T:EFT:E\rightarrow F be a non-necessarily continuous triple homomorphism from a (complex) JB^*-triple (respectively, a (real) J^*B-triple) to a normed Jordan triple. The following statements hold: (1) TT has closed range whenever TT is continuous (2) TT has closed range whenever TT is continuous This result generalises classical theorems of I. Kaplansky and S.B. Cleveland in the setting of C^*-algebras and of A. Bensebah and J.P\'erez, L. Rico and A. Rodr'\iguez Palacios in the setting of JB^*-algebras.
