Asymptotic freedom with discrete spin variables?
Peter Hasenfratz, Ferenc Niedermayer
We study the critical behaviour of the 2d dodecahedron spin model and investigate the conjecture that the discrete model describes the same continuum theory as the O(3) non-linear…

The theoretical background and properties of perfect actions
Peter Hasenfratz
This lecture note starts with a pedagogical introduction to the theoretical background and properties of perfect actions, gives some details on topology and instanton solutions and…
