On the higher order geometry of Weil bundles over smooth manifolds and over parameter-dependent manifolds

(Lobachevskii Journal of Mathematics, Vol.18, pp.53-105 )

The Weil bundle TA Mn of an n-dimensional smooth manifold Mn determined by a local algebra A in the sense of A. Weil carries a natural structure of an n-dimensional A-smooth manifold. This allows ones to associate with TA Mn the series Br(A)TA Mn , r=1,∞, of A-smooth r-frame bundles. As a set, Br(A)TA Mn consists of r-jets of A-smooth germs of diffeomorphisms (An,0) → TA Mn. We study the structure of A-smooth r-frame bundles. In particular, we introduce the structure form of Br(A)TA Mn and study its properties.
Next we consider some categories of m-parameter-dependent manifolds whose objects are trivial bundles Mn× Rm→ Rm, define (generalized) Weil bundles and higher order frame bundles of m-parameter-dependent manifolds and study the structure of these bundles. We also show that product preserving bundle functors on the introduced categories of m-parameter-dependent manifolds are equivalent to generalized Weil functors.
