Über dieses Buch

Starting at an introductory level, the book leads rapidly to important and often new results in synthetic differential geometry. From rudimentary analysis the book moves to such important results as: a new proof of De Rham's theorem; the synthetic view of global action, going as far as the Weil characteristic homomorphism; the systematic account of structured Lie objects, such as Riemannian, symplectic, or Poisson Lie objects; the view of global Lie algebras as Lie algebras of a Lie group in the synthetic sense; and lastly the synthetic construction of symplectic structure on the cotangent bundle in general. Thus while the book is limited to a naive point of view developing synthetic differential geometry as a theory in itself, the author nevertheless treats somewhat advanced topics, which are classic in classical differential geometry but new in the synthetic context.
Audience: The book is suitable as an introduction to synthetic differential geometry for students as well as more qualified mathematicians.

Chapter 1. Differential calculus and integrals
Abstract
Mathematicians or physicists often speak, with some neglect, of first order approximation, as if they were manipulating numbers d so small that they have null square.
René Lavendhomme
Chapter 2. Weil algebras and infinitesimal linearity
Abstract
We encountered in 1.1 various small objects, the most typical and simple one being D. We intend to indicate in this section a more algebraic view of these small objects.

Chapter 3. Tangency
Abstract
Let M be a microlinear object and m a point in M. Classically, a tangent vector at a point m in a differentiable manifold M can be described as an equivalence class of curves passing through m, two arcs being considered equivalent if their expressions in local coordinates have the same derivatives. But here, as we look at things in the infinitesimal — we are in the infinitesimal context — we can identify a tangent vector with an infinitesimal shifting, in other words with a “micro-arc” defined only on D.

Chapter 4. Differential forms
Abstract
Let M be a microlinear object and E be a microlinear Euclidean R-module. A differential n-form on M with value in E will be a function that associates to every n-microcube on M an element of E and this in an n-linear and alternated way, in a sense that will be specified.

Chapter 5. Connections
Abstract
An important problem in differential geometry is how one can compare tangent vectors at one point to those at another, at least in the case of nearby points. We ask if, at least during an infinitesimal period of time, it is possible to “transport” a tangent vector in the direction of another tangent vector.

Chapter 6. Global actions
Abstract
It appeared in the thread of preceding chapters that objects defined in a pointwise manner give rise to some global actions. Such was the case of vector fields, differential forms or connections. We will give here a more systematic account of these situations.
René Lavendhomme
Chapter 7. On the algebra of the geometry of mechanics
Abstract
First we define the fundamental concept of Riemannian structure. We must clarify the notion of non-degenerate map, because, in our logic, the function of negation is tricky.
René Lavendhomme
Chapter 8. Note on toposes and models of S.D.G.
Abstract
Here our aim is very different to that of the preceding chapters. In a sense our account of S.D.G. is finished. Now our objective is to show how it is possible to understand the idea of an intuitionistic set theory, or, more precisely, the concept of toposes. We shall also indicate some models of S.D.G., so showing how results can be applied to classical differential geometry.
