Improved actions, the perfect action, and scaling by perturbation theory in Wilsons renormalization group: the two dimensional -invariant non linear -model in the hierarchical approximation
C. Wieczerkowski, Y. Xylander
We propose a method using perturbation theory in the running coupling constant and the idea of scaling to determine improved actions for lattice field theories combining Wilson's r…

Conformal blocks on elliptic curves and the Knizhnik--Zamolodchikov--Bernard equations
Giovanni Felder, Christian Wieczerkowski
We give an explicit description of the vector bundle of WZW conformal blocks on elliptic curves with marked points as subbundle of a vector bundle of Weyl group invariant vector va…

Nonassociative Algebras and Nonperturbative Field Theory for Hierarchical Models
A. Pordt, C. Wieczerkowski
Hierarchical renormalization group (RG) transformations are related to nonassociative algebras. These algebras serve as a new basic tool for a rigorous treatment of global RG flows…
