Integration à la Harish-Chandra for bi-graded Lie algebras

Alexei Kotov, Vladimir Salnikov, Olga Salnikova Chekeres

We study ${\mathbb{Z}}_2\times {\mathbb{Z}}_2$ bi-graded Lie algebras. We describe their properties in relation to Lie superalgebras with some compatible structures. Then we focus on the…
