The main subject of this course is the homology and cohomology groups of CW complexes and manifolds. We introduce a CW complex, its properties, singular and cellular homology and cohomology groups of a CW complex. Next we explain the homology and cohomology groups of a manifold, their duality and products in cohomology groups. This course is a succession of “Advanced courses in Geometry C” in the third quarter.
CW complexes and manifolds are important objects of topology and geometry. The general properties of the homology and cohomology groups of CW complexes and manifolds play an important role to calculate the homology and cohomology groups of a given manifold or a CW complex, and to understand its properties. This course aims to grasp the properties of homology and cohomology groups of CW complexes and manifolds.
By the end of this course, students will be able to:
・understand the definition of each term concerning the following "keywords"
・grasp the properties of homology and cohomology groups of CW complexes and manifolds
・calculate homology and cohomology groups of some CW complexes and manifolds.
cell complex, CW complex, homology theory, cohomology theory, cellular homology theory, cellular cohomology theory, manifold, duality, cup product
