Abstract:

Motivated by applications of twisted current algebras in description of the entropy of

Ads_3

black hole, we investigate the simplest twisted current algebra

sl(3,{\bf C})^{(2)}_k

. Free field representation of the twisted algebra and the corresponding twisted Sugawara energy-momentum tensor are obtained by using three

(\beta,\gamma)

pairs and two scalar fields. Primary fields and two screening currents of the first kind are presented.
