The existence of superinvolutions

Abstract: Superinvolutions on graded associative algebras constitute a source of Lie and Jordan superalgebras. Graded versions of the classical Albert and Albert-Riehm Theorems on the existence of superinvolutions are proven. Surprisingly, the existence of superinvolutions of the first kind is a rare phenomenon, as nontrivial central division superalgebras are never endowed with this kind of superinvolutions.

“…We recall a theorem of Albert-Reihm on the existence of K/k -involution (involution of the second kind) which states that JABER finite dimensional central simple algebra A over K has a K/k -involution if and only if the corestriction of A splits over k . In [1] A. Elduque and O. Villa gave a much better exposition and motivation for the whole theory of the existence of superinvolutions.…”

“…Motivado pelo que é apresentado em [16], [19], [22] e [26], Racine em [25] mostra resultados estruturais análogos para superanéis. Em [12], Villa prova a existência de superinvoluções em superálgebras primitivas. Já em [25], Racine também apresenta dois teoremas: [Theorem 6] e [ Theorem 7].…”

“…Nós podemos observar que casos particulares de σ-involuções (involuções graduadas, superinvoluções, involuções coloridas, etc) aparecem em vários estudos. Motivados por essa teoria desenvolvida em [1], [12], [22] e [25], nosso trabalho seguirá nessa linha. Estudamos a estrutura de anéis G-graduados primitivos à direita e F -álgebras G-graduadas primitivas à direita com um ideal à direita G-graduado minimal.…”
