The aim of this paper is to start a systematic investigation of the existence of angular limits and angular derivatives of holomorphic maps of infinite dimensional Siegel domains in \( J^{*} \)-algebras. Since \( J^{*} \)-algebras are natural generalizations of \( C^{*} \)-algebras, \( B^{*} \)-algebras, \( JC^{*} \)-algebras, ternary algebras and complex Hilbert spaces, various significant results follow. Examples are given.
Questo articolo ha lo scopo di avviare uno studio sistematico dell'esistenza di limiti e derivate angolari di mappe olomorfe di domini di Siegel di dimensione infinita in algebre \( J^{*} \). Poiché le algebre \( J^{*} \) sono generalizzazioni naturali di algebre \( C^{*} \), algebre \( B^{*} \), algebre \( JC^{*} \), algebre ternarie e spazi di Hilbert complessi, ne seguono diversi risultati significativi. Vengono esaminati alcuni esempi.
