A homotopy BV algebra for Yang-Mills and color-kinematics

Standard Feynman rules for Yang-Mills tree amplitudes fail to comply with the Bern-Carrasco-Johansson/color-kinematics duality. I will make the point that this failure is due to homotopies. These homotopies are local multilinear operations that jointly define a homotopy Batalin-Vilkovisky algebra structure for Yang-Mills on Minkowski spacetime, an algebraic upgrade of standard Yang-Mills. When this homotopy BV structure is rectified, it yields Feynman rules that do comply with BCJ/color-kinematics duality. All relevant algebraic terminology will be introduced from scratch.
