Description
Symmetries underlie physics. Often, symmetries do not hold exactly but
only "up to homotopy" (often synonymous with "on shell"), and this
corresponds to the mathematical structure of homotopy algebras (e.g.
L∞-algebras). We explore some of the many instances where such structures appear, including colour-kinematics duality, holomorphic twists, the
Keldysh-Schwinger formalism, and the AdS/CFT correspondence, as time
permits, and how to construct recursion formulas using them.
