Opis

The current state of knowledge on the Monster group, including Majorana theory, Vertex Operator Algebras, Moonshine and maximal subgroups.

Recenzje

''Monstrous Moonshine', an unexpected correspondence involving the largest sporadic simple group, the classical modular function, and conformal field theory, was one of the greatest discoveries of the twentieth century. The modern approach, pioneered by Alexander Ivanov, involves Majorana algebras; the theory is clearly explained here. Among other jewels in the book is a geometric discussion of the Freudenthal - Tits 'magic square', linking the exceptional Lie algebras with the real, complex, quaternion and octonion number fields.' Peter Cameron, University of St Andrews
