英文摘要:

In this paper, \thinspace \thinspace we generalize the concepts of \thinspace level \thinspace and \thinspace sublevel of a composition algebra to algebras obtained by the Cayley-Dickson process. In 1967, R. B. Brown constructed, for every}$t\in \Bbb{N},${\small % \ a division algebra}$A_{t}${\small \ of dimension}$2^{t}${\small \ over the power-series field}$K\{X_{1},X_{2},...,X_{t}\}.\,${\small \ This gives us the possibility to construct a division algebra of \thinspace dimension \thinspace 2}$^{t}\,${\small and prescribed \thinspace level and sublevel \thinspace \thinspace 2}$^{k}${\small ,\thinspace \thinspace}$k,\,t\in \Bbb{% N}^{*}${\small \ and a division algebra of \thinspace dimension \thinspace}$% 2^{t}+1,t\in \Bbb{N}\,${\small and prescribed \thinspace level and sublevel}% $\,2^{k}+1,k\in \Bbb{N}.\,\medskip $
