Construction of new supergroups with non-simple or non-listed simple Lie superalgebras.
Extension of known supergroup structures beyond Kac's theorem.
Abstract
We describe certain almost-simple algebraic supergroups over an algebraically closed field of odd or zero characteristic. In addition to supergroups with simple Lie superalgebras from Kac's theorem, we construct new supergroups whose Lie superalgebra is either non-simple or simple but is not part of Kac's list.
