Influence of network disorder and degree distribution on voter model dynamics

Voter model is a very simple model of opinion formation. We study it\\\'s
dynamics in scale-free networks, where it hasn\\\'t been studied before, and
several other kinds of networks. From that observations, we conclude on
how degree distribution of network and ist\\\'s disorder influences the
dynamics, in both qualitative and quantitative way.
We also studied a case of a zealot - a single node in the network that do
not change it\\\'s state, but influences neighborhood normally. The influence
of such a node on voter model dynamics in Barabasi-Albert network is
discussed.
