These are voter model like processes with the difference that the edges are considered to be either positive or negative. If an edge between a site $x$ and a site $y$ is negative (respectively positive) the site $y$ will contribute towards the flip rate of $x$ if and only if the two current spin values are equal (respectively opposed).22 pagesProbability60K35, 82C22 (Primary); 60G50, 60G60, 60J10 (Secondary)text
