In mathematics, a connector is a map which can be defined for a linear connection and used to define the covariant derivative on a vector bundle from the linear connection.
Let â be a connection on the tangent space TN of a smooth manifold N. For smooth mappings h:MâÂÂTN from any smooth manifold M, the connector K:TTNâÂÂTN satisfies : â h = KâÂÂTh:TMâÂÂTN where Th:TMâÂÂTTN is the differential of h.
