On almost polynomial structures from classical linear connections

Abstract

Let Mfm be the category of m-dimensional manifolds and local diffeomorphisms and let T be the tangent functor on Mfm. Let V be the category of real vector spaces and linear maps and let Vm be the category of m-dimensional real vector spaces and linear isomorphisms. Let w be a polynomial in one variable with real coefficients. We describe all regular covariant functors F : Vm -> V admitting Mfm-natural operators P transforming classical linear connections r on m-dimensional manifolds M into almost polynomial w-structures P(r) on F(T)M = Ux2M F(TxM).
