广义三重同态与导子

Generalised triple homomorphisms and Derivations

Jorge J. Garcés, Antonio M. Peralta

AI总结:

该研究引入Jordan Banach三重系统上的广义三重同态与广义三重导子概念,证明了JB$^*$-三重上两类映射的自动连续性,推广了已有Banach代数相关结果。

摘要:

我们引入Jordan Banach三重系统之间的广义三重同态概念,该概念推广了Jarosz与Johnson分别于1985年、1987年提出的Banach代数之间的广义同态概念。我们证明,JB$^*$-三重之间的每一个广义三重同态都自动连续。当限定到C$^*$-代数的情形时,我们重新得到了Johnson证明的一个主要定理。我们还将考虑从Jordan Banach三重$E$到Jordan Banach三重$E$-模的广义三重导子,证明从JB$^*$-三重$E$到$E^*$的每一个广义三重导子都自动连续。

英文摘要:

We introduce generalised triple homomorphism between Jordan Banach triple systems as a concept which extends the notion of generalised homomorphism between Banach algebras given by Jarosz and Johnson in 1985 and 1987, respectively. We prove that every generalised triple homomorphism between JB$^*$-triples is automatically continuous. When particularised to C$^*$-algebras, we rediscover one of the main theorems established by Johnson. We shall also consider generalised triple derivations from a Jordan Banach triple $E$ into a Jordan Banach triple $E$-module, proving that every generalised triple derivation from a JB$^*$-triple $E$ into $E^*$ is automatically continuous.
