Course description and aims

The aim of this course is to familiarize the students with basic notions and properties on differentiable manifolds, which are important not only in mathematics but in related areas such as theoretical physics. It is not easy for beginners to comprehend these abstract notions without suitable training. We supply many concrete examples in each lecture.
The contents of this course are as follows: definition and examples of manifolds, smooth functions on manifolds, smooth maps between manifolds, constructing manifolds by using the inverse images of regular values, definition of tangent vectors and tangent spaces, differentials of maps, regular values, critical points, inverse function theorem, Sard's theorem, immersions and embeddings, submanifold, partition of unity, vector fields.
We strongly recommend to take this course with [ZUA. B302 : Exercises in Geometry B I].
