### Course description and aims

The aim of this course is to familiarize the students with basic notions and properties on diferentiable manifolds, which are important not only in mahematics 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 is 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. Each lecture will be accompanied by a problem solving class. This course will be succeeded by [MTH. B302 : Geometry II] in the second quater.

### Student learning outcomes

Students are expected to
・understand the definition of manifolds.
・know more than 5 examples of manifolds.
・understand the definitions of smooth functions on manifolds, and smooth maps between manifolds.
・be familiar with the method of constructing manifolds by using the inverse images of regular values.
・understand the definition of tangent vectors and tangent spaces.
