Abstract
Consider a topologically transitive countable Markov shift and a summable Markov potential with finite Gurevich pressure and . We prove existence of the limit in the weak topology, where is the unique equilibrium state associated to the potential . Besides that, we present examples where the limit at zero temperature exists for potentials satisfying more general conditions.
