Starting from Borcherds' fake monster Lie algebra, this text construct a sequence of six generalized Kac-Moody algebras whose denominator formulas, root systems

This book provides the reader with the tools to understand the ongoing classification and construction project of Lie superalgebras. It presents the material in
Koszul rings are graded rings which have played an important role in algebraic topology, noncommutative algebraic geometry and in the theory of quantum groups.
