• Problem 1 studies the space of connections, and proves that this is an affine space modelled on $\Omega^1(M, \operatorname{End}(E))$.
• Problem 2 relates $d^{ \nabla}$ and $d^{ \nabla^{ \operatorname{End}}}$.
• Problem 3 introduces the idea of a $G$-connection.
• Problem 4 shows that the holonomy group of a Riemannian connection is a subroup of the orthogonal group.
• Problem 5 introduces the musical isomorphisms[1] between a Riemannian vector bundle and its dual.
• Problem 6 asks you to prove that characterisic classes of odd degree invariant polynomials are always zero.
• Problem 7 asks you to verify that the Chern-Weil homomorphism is indeed a homomorphism.
• Problem 8 is the Whitney product formula. Remark: The statement would be more complicated if one worked with cohomology with coefficients in $\mathbb{Z}$.
• Problem 9 asks you to compute the Pontryagin classes of $TS^m \to S^m$.
