A supercritical series analysis for the generalized contact process with diffusion
W. G. Dantas, J. F. Stilck
We study a model that generalizes the CP with diffusion. An additional transition is included in the model so that at a particular point of its phase diagram a crossover from the d…

A two-variable series for the contact process with diffusion
W. G. Dantas, M. J. de Oliveira, J. F. Stilck
In this work we use the technique of the partial differential approximants to determine, from a pertubative supercritical series expansion for the ulimate survival probability, the…
