Introduction,overing homotopy method which, following M. Gromov’s thesis , is also referred to as the method of sheaves. The covering homotopy method is due originally to S. Smale who proved a crucial covering homotopy result in order to solve the classification problem for immersions of spheres in Euclidean space.

Analytic Theory,tions Γ(.) is identified naturally with .°(.,..). Let . ∈ Γ(.). Employing the splitting of ., one defines the derivative map ∂.. : . → .. where . ∈ and ∂. = ∂/∂.. A section . ∈ Γ(.) is .. in . if ∂.. ∈ Γ(.). Let ∥ ∥ be the sup-norm on .°(., ..).

Hans Müller-Steinhagen Prof. Dr.-Ing.es of 1-jets .. since in local coordinates first order derivatives are all pure. As mentioned in the introduction to Chapter IV, by suitable local changes of coordinates it is possible to apply this technique also in the case of open, ample relations in 2-jet spaces .., although we have not attempted to develop the details in this book.

Michael Kleiber Dr.,Ralph Joh Dr. rer. Nat.omic. The .-principle is required to be a relative condition in the following sense. Let . ⊂ . be closed and suppose α is holonomic on .: there is a ..-section . ∈ Γ(.) such that . = .. ∈ Γ.(.(.)). Then in addition we require that for all . ∈ , ..= α ∈ Γ.(.) (constant homotopy over .).
