    "abstract": "This work builds on the Volterra series formalism presented in [D. W.\nDreisigmeyer and P. M. Young, J. Phys. A \\textbf{36}, 8297, (2003)] to model\nnonconservative systems. Here we treat Lagrangians and actions as `time\ndependent\u0027 Volterra series. We present a new family of kernels to be used in\nthese Volterra series that allow us to derive a single retarded equation of\nmotion using a variational principle.",
