Abstract
We consider Regge calculus in the representation in terms of area tensors and self- and antiselfdual connections generalised to the case of Holst action that is standard Einstein action in the tetrad-connection variables plus topological (on equations of motion for connections) term with coefficient , is Barbero-Immirzi parameter. The quantum measure is shown to exponentially decrease with areas with typical cut-off scales and in spacelike and timelike regions, respectively ( is the Newton constant).
