Handout: Homological Algebra

46. Homological Algebra

• Description: The study of homology and cohomology theories in algebraic topology and abstract algebra, providing tools to investigate algebraic structures.
• Key Points:
  • Definitions:
    • Chain Complex: A sequence of abelian groups connected by homomorphisms with the property that the composition of two consecutive maps is zero.
    • Exact Sequence: A sequence of abelian groups and homomorphisms where the image of one homomorphism equals the kernel of the next.
  • Properties:
    • Homology Groups: Measure the failure of a sequence to be exact, providing invariants of topological spaces.
    • Cohomology Groups: Dual concept to homology groups, often with additional algebraic structure.
  • Formulas:
    • Homology Group: $H_n(C) = \frac{\ker \partial_n}{\text{im} \partial_{n+1}}$
• Examples:
  • Basic Example: Homology groups of a simple polyhedron.
  • Complex Example: Computing the cohomology of a torus.
• Visual Aids:
  • Diagram: Chain complex showing homomorphisms and exact sequences.
• Applications:
  • Real-world Uses:
    • Algebraic topology (classifying spaces)
    • Algebraic geometry (derived functors)
