Deformations of Symmetric Simple Modular Lie (Super)Algebras
Deformations of Symmetric Simple Modular Lie (Super)Algebras
We say that a Lie (super)algebra is ''symmetric'' if with every root (with respect to the maximal torus) it has the opposite root of the same multiplicity. Over algebraically closed fields of positive characteristics (up to 7 or 11, enough to formulate a general conjecture), we computed the cohomology corresponding …
