l-REDUCTION AND TWISTED CONFORMAL FIELD THEORY

Abstract: Theory of l-reduction of KP hierarchy is investigated from a view point of conformal field theory. Twisted conformal field theory emerges naturally in the discussion. Possible application of this kind of connection between hierarchy and CFT is suggested.

Renormalization of Field Theories in Riemann-Cartan Space-Time

Abstract: Eiemann-Cartan geometry with curvature and torsion arises naturally within the framework of Poincare gauge theory of gravity The simplest example is given by the Einstein-Cartan theory (Kibble, 1961; Sciama, 1962; Trautman, 1973; Hehl et al, 1976) in which the coupling of spin and torsion is realised in a degenerate algebraic manner More general models are based on the Yang-Mills type Lagrangians, quadratic both in torsion and curvature Classical dynamics of the Poincare gravitational fields is at present intensively studied (some bibliography can be found in books by Ivanenko et al, (1985) and Ponomariev et al (1985))
