Ancestral lineages under horizontal trait transfer: spinal decomposition and time reversal beyond stationarity
This work replaces in the interactions the original stochastic process with the deterministic large population approximation obtaining a nonhomogeneous measure-valued branching process, for which it uses a spinal decomposition, generalizing a method that existed only for the stationary case.
