Structure of Coset Models
Soeren Koester
We study inclusions of local, chiral, conformal quantum theories C which are contained in an ambient theory B and commute with another given subtheory A. These subtheories C are ca…

Absence of stress energy tensor in CFT_2 models
Soeren Koester
We prove: the quantum field theories defined by conformally covariant derivatives of the U(1)-current algebra in 1+1 dimensions do not contain a stress energy tensor in the sense o…
