  These notes are intended as a fairly self contained explanation of Fock space
and various algebras that act on it, including a Clifford algebra, a Weyl
algebra, an infinite rank matrix algebra, and an affine Kac-Moody algebra. We
also discuss how the various algebras are related, and in particular describe
the celebrated boson-fermion correspondence. We finish by briefly discussing a
deformation of Fock space, which is a representation for the quantized
universal enveloping algebra of affine sl(n).
