A generalized correlated random walk is a process of partial sums $X_{k}=\sum_{j=1}^{k}Y_{j}$ such that (X, Y) forms a Markov chain. For a sequence (Xn) of such ...
We show that several diffusion-based approximations (classical diffusion or SP1, SP2, SP3) to the linear Boltzmann equation can (for an infinite, homogeneous medium) be represented exactly by a ...
