The main subject of this course is the homology and cohomology theories of topological spaces with coefficients in a general module. After reviewing integral homology groups of a simplicial complex, we introduce homology and cohomology groups with coefficients in a module, singular homology and cohomology groups with coefficients in a module, its axioms, and its application. This course will be succeeded by “Advanced courses in Geometry D” in the fourth quarter.
Homology and cohomology groups are basic tools among topology, geometry, algebra, and analysis. This course aims to grasp the fundamental concept and properties of homology and cohomology theories.
By the end of this course, students will be able to:
・understand the definition of each term concerning the following "keywords"
・grasp the main ideas of the homology and cohomology theories
・calculate homology and cohomology groups of some spaces
homology and cohomology groups with coefficients in a module, chain complex, cochain complex, cycle, boundary, homotopy, exact sequence, excision
