HuberAbstractInallgaugetheories, includinggeneralrelativity, paralleltransportersareoffundamental importance. They are unitary maps between vector spaces atdierent space time points. It is proposed to abandon unitarity as a generalrequirement. The proposal is motivated by the fact that in discrete calculusand di erential geometry unitarity is not a natural requirement, and by adesire to interpret Higgs elds geometrically.The present thesis discusses gauge theories with nonunitary paralleltransport both in the continuum and on a graph.Vierbein elds can be identi ed as parts of nonunitary parallel trans-porters in the conventional four space time dimensions. Assuming invert-ibility of the parallel transporters it is shown how general relativity ts intothisframework. Metricityisobtainedautomaticallywithoutneedtoassumeit.
