ANNIHILATOR ALTERNATIVE ALGEBRAS I. P. DE GUZMAN The aim of this paper is to use in the alternative case the axioms of the annihilator Banach algebras, and obtain some structure theorems similar to the known ones in the associative case.
1. Introduction. As corollary of the main theorem of this paper: Theorem 3.11, we prove (see Corollary 3.12) that if A is a Kleinfeld semisimple annihilator complex purely-alternative algebra, then A is the closure of the direct sum of all its ideals which are isomorphic to the algebra of complex octonions θ c . 2. Prerequisites and notation. In this paper, A is always understood to be an alternative algebra. "Ideal" without further qualification will mean "ideal of A". (2.1) N(A) denote the nucleus of A (for the definition of N(A)9 see for example [3]). We say an ideal (or right ideal or left ideal) / is nuclear provided {0} ΦI
