On Moduli Spaces for Finite-Order Jets of Linear Connections

Adrian Gordillo, Jose Navarro


We describe the ringed--space structure of moduli spaces of jets of linear connections (at a point) as orbit spaces of certain linear representations of the general linear group.Then, we use this fact to prove that the only (scalar) differential invariants associated to linear connections are constant functions, as well as to recover various expressions appearing in the literature regarding the dimensions of generic strata of these moduli spaces.
