## An Introduction to Differential Manifolds

Solutions to the Final Exam have been posted here. The grades of the Final Exam as well as the overall grades for the course are available here. You can come by my office Wednesday, December 18, at 5 pm, to look at your Final Exam. Syllabus: Foundations of Differentiable Manifolds. Differentiable manifolds and differentiable maps.

The exact definition of this pushforward depends on the definition one uses for tangent vectors for the various definitions see tangent space. If one defines tangent vectors as equivalence classes of curves through x then the differential is given by.

Alternatively, if tangent vectors are defined as derivations acting on smooth real-valued functions, then the differential is given by. Therefore, in some chosen local coordinates, it is represented by the Jacobian matrix of the corresponding smooth map from R m to R n. In general the differential need not be invertible.

It follows from the definition that the differential of a composite is the composite of the differentials i. This is the chain rule for smooth maps. Also, the differential of a local diffeomorphism is a linear isomorphism of tangent spaces.

It also contains 66 gures. The book is organized as follows. The rst three chapters comprehend all the topics included in an standard course on dierentiable manifolds at an un- dergraduate level, starting from the very denition of a dierentiable manifold, passing through its tensor algebra, and ending with integration on manifolds and de Rham cohomology. This rst part is of great value for both students and teachers.

The second part of the book is devoted to Lie groups, Rieman- nian geometry and bre bundles, subjects that must be part of a dierential geometer's background.
