The amended KSh conjecture for modular Lie algebras and Lie superalgebras

Let p>0p>0. Consider simple finite dimensional Lie algebras and Lie superalgebras, including Z\mathbb{Z}-graded and non-graded examples. The KSh procedure is applied to every simple complex Lie algebra of type (1); when p=2p=2, it is also applied to the relevant simple complex Lie superalgebras and their simple Volichenko subalgebras. In characteristic 22, queerification and Jurman's examples are additionally included. From the resulting simple finite dimensional Z\mathbb{Z}-graded algebras, together with the exceptional algebras g(A)\mathfrak{g}(A) for p=5,3,2p=5,3,2, take non-positive parts, their complete and partial prolongations, and simple subquotients; non-graded examples are obtained by allowing deformations of the resulting algebras and Shen's variations.

Amended KSh conjecture. These constructions yield all Z\mathbb{Z}-graded simple finite dimensional examples of Lie algebras and Lie superalgebras in characteristic p>0p>0, while the indicated deformations and Shen's variations yield the non-graded examples.

This is a proposed classification framework incorporating the characteristic-22 superization, queerification, Jurman's constructions, exceptional algebras, prolongations, subquotients, deformations, and Shen's variations. The source gives no resolution, so the conjecture remains open.
