Section outline

  • Lecture 11:

    • Flows of smooth vector fields: fundamental theorem and examples of (non)global flows
    • Complete vector fields: definition and (non)examples
    • The cotangent bundle of a smooth manifold
    • Differential 1-forms aka smooth covector fields (= smooth sections of the cotangent bundle)
    • The differential of a smooth function

    Info: For various nice pictures of flows of smooth vector fields, see Integral Curves (p. 207) and Regular Points and Singular Points (p. 221).

    Important info: This week's exercise session is cancelled; see Linus' email (26.11.2025, 16:13) for useful info regarding its replacement.
