Exploring the Relationship Between Metric and Connection Fields in Einstein-Kartan Theory

This chapter analyzes the technical aspects of general relativity, focusing on the derivation of curvature from the metric in Einstein-Kartan theory. It details the introduction of the torsion tensor as an independent component of the connection and delves into the implications of making torsion a non-propagating field. The discussion also touches on the historical context, skepticism towards avoiding singularities in gravity, and the perspective of quantum field theorists on torsion fields.
