Coset conformal field theory

In theoretical physics
, a coset conformal field theory is a conformal field theory
that describes the degrees of freedom not included in a smaller conformal field theory H but included in a bigger conformal field theory G. The coset is called G/H and its stress-energy tensor is a difference of the tensors from G minus the tensor from H whenever the coset can be constructed.
The coset CFT is often used together with the Sugawara theory.
