  • Vector spaces
    • Definition
    • Examples -- F, Fn, F[x], F[x,y], {f(x,y) | deg f=n}
    • Linear independence
    • Spanning
    • Bases
    • Dimension
    • Subspaces
    • Sums of subspcaes
    • Direct sums
    • Quotient spaces
  • Linear transformations
    1. Definition
    2. Kernel and image
    3. Isomorphism
    4. Eigenspaces, eigenvectors, and eigenvalues
    5. Hom(V,W) is a vector space
    6. V*=Hom(V,F)
    7. V* is isomorphic to V if and only if V is finite dimensional.
    8. End(V)
    9. GL(V)
    10. Exact sequences
  • Other constructions
    1. Sums, direct sums, and tensor products
    2. Bilinear forms
      1. Symmetric and skew-symmetric forms
      2. Radical, nondegenerate bilinear forms
      3. Relation with linear functionals
  • Matrices
    1. of a linear transformation
    2. of an endomorphism
    3. of a bilinear form
  • Equivalence relations and bilinear forms
    1. Equivalence
    2. Similarity
    3. Contragradience

    Toto, are we still in Kansas?
