Preface It is a striking fact that differential calculus exists not only in analysis (based on the real numbers R), but also in algebraic geometry, where no limit processes are available. In algebraic geometry, one rather uses the idea of nilpotent elements in the " affine line " R; they act as infinitesimals. (Recall that an element x in a ring R is called… (More)

For any locally cartesian closed category , we prove that a local fibered right adjoint between slices of is given by a polynomial. The slices in question are taken in a well known fibered sense.

The theory of combinatorial differential forms is usually presented in simplicial terms. We present here a cubical version; it depends on the possibility of forming affine combinations of mutual neighbour points in a manifold, in the context of synthetic differential geometry.
