Abstract. We consider free Bosons hopping on a network(infinite graph).
The condition for Bose-Einstein condensation is given in terms of the
random walk on a graph. In case of periodic lattices, we also consider
Boson moving in an external periodic potential and obatined the criterion
for Bose-Einstein condensation.
