Notes on supersymmetric and holomorphic field theories in dimensions 2 and 4

These notes explore some aspects of formal derived geometry related to classical field theory. One goal is to explain how many important classical field theories in physics—such as supersymmetric gauge theories and supersymmetric $\sigma$-models—can be described very cleanly using derived geometry. In particular, I describe a mathematically natural construction of Kapustin-Witten’s $\mathbb{P}^1$ of twisted supersymmetric gauge theories.
