Description:

Differentiable manifolds are among the most fundamental notions of modern mathematics. Roughly, they are geometrical objects that can be endowed with coordinates; by using coordinates one can apply on them differential and integral calculus, but the results are coordinate-independent. Examples of manifolds start with open domains in Euclidean space Rn and "multi-dimensional surfaces" such as the n-sphere Sn and n-torus Tn. In principle, every manifold of dimension n can be visualized as an "n-dimensional surface" in a Euclidean space RN for some large N. Besides spheres and tori, classical examples include the projective spaces RPn and CPn, matrix groups such as the rotation group SO(n), the so-called Stiefel and Grassmann manifolds, and many others. Differentiable manifolds naturally arise in various applications, e.g., as configuration spaces of physical systems or as space-time. They are arguably the most general objects on which calculus can be developed and they provide for it a powerful invariant geometric language, which is used in almost all areas of mathematics and its applications.

Details of prerequisites: Standard calculus and linear algebra; familiarity with the statement of the implicit function theorem (students may consult any good textbook in multivariate calculus); some familiarity with algebraic concepts such as groups and rings is desirable, but no knowledge of group theory or ring theory is assumed; some familiarity with basic topological notions (topological spaces, continuous maps, Hausdorff property, connectedness and compactness) may be beneficial, but is not assumed.

Textbooks: No particular textbook is followed. Students are advised to keep their own lecture notes and study my notes posted on the web. Solving problems is essential for understanding. There are many good sources available treating various aspects of differentiable manifolds on various levels and from different viewpoints. Below is a list of texts that may be useful. More can be found by browsing library shelves.
