  The goal of these lectures is to exhibit the framing anomaly in the
Batalin-Vilkovisky formulation of perturbative Chern-Simons theory. Concretely,
we show that the partition function fails to satisfy the Quantum Master
Equation, and show that this can be remedied at the cost of introducing a
framing. Along the way, we discuss principal bundles and connections, the
Chern-Simons action functional, and perturbative quantization of gauge theories
in the Batalin-Vilkovisky formalism.
