Monstrous moonshine
In mathematics, monstrous moonshine, or moonshine theory, is the unexpected connection between the monster group M and modular functions, in particular, the j function. The term was coined by John Conway and Simon P. Norton in 1979.[1][2][3]
The monstrous moonshine is now known to be underlain by a vertex operator algebra called the moonshine module (or monster vertex algebra) constructed by Igor Frenkel, James Lepowsky, and Arne Meurman in 1988, which has the monster group as its group of symmetries. This vertex operator algebra is commonly interpreted as a structure underlying a two-dimensional conformal field theory, allowing physics to form a bridge between two mathematical areas.

Introduction. The theories of Kac-Moody algebras and dual resonance
models were born at approximately the same time (1968). The second
theory underwent enormous development until 1974 (see reviews [25, 26])
followed by years of decliae, while the first theory moved slowly until the
work of Kac [14] in 1974 followed by accelerated progress.
