Algebraic Combinatorics and the Monster Group

Alexander A. Ivanov earned his PhD degree in mathematics in 1984 from the Moscow Physical Technical Institute. He was a researcher at Institute for System Analysis and received Doctor of Science degree from Moscow State University in 2000. Since 1995, Professor Ivanov has taught at the Imperial College London. He gave an invited talk at 1990 ICM in Kyoto and authored five monographs.

'Describing the Monster group mathematical structures is the culmination of decades of work. Just as the largest Mathieu group framed the 24-dimensional Leech lattice, so also that lattice is the foundation for constructing the Moonshine Module and the Monster algebra, through which the Monster has become central in a theory with deep connections to modern physics. The first part of the book is a collection of five papers on the Monster and other algebraic structures, presented by international leaders in the area providing an outsider with the necessary content and concepts. It presents an account of the current status of the theory and available computational tools for studying the Monster and its algebras. The machinery for developing Majorana theory and axial algebras underpinning the Monster is based on Algebraic Combinatorics, to which the second part of this collection is devoted.'
