Abstract
A construction of a kth structure tensor of a field of geometric objects is presented here (k is a non-negative integer). For a given field σ we construct a vector bundle H k,2(σ). The kth structure tensor is defined as a section of H k,2(σ) generated by the torsion of σ. It is then shown that vanishing of the kth structure tensor is a necessary and sufficient condition for the field to be (k+1)-flat.
