A BV approach to double copy.
Color kinematics duality is a feature of gauge theories that
appears in the computation of physical amplitudes. Its most relevant application
is the construction of the double copy theory. We discuss the underlying algebraic structure from the
point of view of Batalin-Vilkovisky in the simplified (but meaningful) case of the off shell duality that was highlighted first
for Chern-Simons. Time permitting, we also discuss the gravitational interpretation of the double copy. This talk is based on joint work with M.Ben Shahar and M. Zabzine.
