A new approach to the representation theory of the symmetric groups. IV. ${\mathbb{Z}}_2$-graded groups and algebras

Abstract

We start with definitions of the general notions of the theory of ${\mathbb{Z}}_2$-graded algebras. Then we consider theory of inductive families of ${\mathbb{Z}}_2$-graded semisimple finite-dimensional algebras and its representations in the spirit of approach of the papers \cite{VO,OV} to representation theory of symmetric groups. The main example is the classical - theory of the projective representations of symmetric groups.
