Description
In this talk I show how the canonical formulation of QCD can be
obtained from transfer matrices defined directly in the canonical
sectors of QCD. These transfer matrices are closely related to the
dimensionally reduced Wilson fermion determinant and provide a
complete temporal factorization of the fermion determinant. In the
heavy-dense limit, the fermionic contributions to the canonical
partition functions can be calculated analytically and I show that the
sign problem is absent at infinitely strong coupling. Finally, I
construct a cluster algorithm which solves the sign problem away from
the strong coupling limit.
