Course description and aims
The main subject of this course is basic concepts of vector bundles. We first explain basic notions for vector bundle, such as section, bundle map, induced bundle, Whitney sum, and subbundle. We next give a classification of the vector bundles over spheres by using clutching functions. We finally introduce Stiefel manifolds, Grassmann manifolds and universal bundles, and prove the classification theorem of vector bundles in terms of classifying spaces and classifying maps.
Vector bundles are one of the fundamental notions in geometry and topology. This course is an introductory course on vector bundles and offers several background knowledge to students who want to study advanced geometry and topology. "Advanced courses in Geometry B" (ZUA.B332) held in 2nd Quarter is a continuation of this course.

- Be able to determine whether a given family of vector spaces is a vector bundle
