Homotopy double copy of noncommutative gauge theories


This talk will summarise recent work attempting to understand how standard noncommutative gauge theories, such as those which arise naturally from string theory, fit into the paradigmof colour-kinematics
duality and the double copy of gauge theory to gravity. The treatment will focus on the elegant formulation of the double copy prescription using homotopy algebras. Along the way we shall encounter some novel noncommutative scalar field theories with rigid colour symmetry that have no commutative counterparts, whose double copies are deformations of some known topological theories such as the special Galileon theory in two dimensions and self-dual gravity in four dimensions.
