Inner ideals, compact tripotents and Čebyšëv subtriples of JB $^{}$ -triples and C $^{}$ -algebras

Fatmah B. Jamjoom, Antonio M. Peralta, Akhlaq A. Siddiqui +1

The aim of this note is to study Čebyšëv JB $^{*}$ -subtriples of general JB $^{*}$ -triples. It is established that if $F$ is a non-zero Čebyšëv JB $^{*}$ -subtriple of a JB $^{*}$ -triple $E$ , t…

Quadratic Conorm and extremally rich JB*-triples

Fatmah B. Jamjoom, Antonio M. Peralta, Akhlaq A. Siddiqui +1

We introduce and study the class of extremally rich JB $^{*}$ -triples. We establish new results to determine the distance from an element $a$ in an extremally rich JB $^{*}$ -triple $E$ t…
