Reductive malcev algebra

Definition

A reductive Malcev algebra is a type of algebra that is characterized by its ability to decompose into simple components, providing a structured framework for understanding its representation theory and geometric properties. In essence, it exhibits properties similar to reductive Lie algebras but within the context of Malcev algebras, which are non-associative structures that generalize certain aspects of algebraic systems. This connection allows for an exploration of the rich structure inherent in these algebras, particularly in relation to their representations and cohomology.
