Invasion threshold in heterogeneous metapopulation networks
Physics Faculty Publications (2007)
We study the dynamics of epidemic and reaction-diffusion processes in metapopulation models with heterogeneous connectivity patterns. In susceptible-infected-removed-like processes, along ...
Field theory of absorbing phase transitions with a nondiffusive conserved ...
Physics Faculty Publications (2000)
We investigate the critical behavior of a reaction-diffusion system exhibiting a continuous absorbing-state phase transition. The reaction-diffusion system strictly conserves ...
