Integration à la Harish-Chandra for Bi-Graded Lie Algebras
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 approach to the Lie group-algebra correspondence based on Harish-Chandra pairs and provide some examples of application of it in the bi-graded setting.
