Title: 
Partition functions for noncommutative lattices

Abstract: 
We develop an abstract theory of partition functions
on noncommutative lattices (i.e. on Cayley graphs of groups).
The space of all partition functions has natural fibration
over the space of all opposite series for the growth fuctions
of the group. If the space is finite, we give a residue formula
for the traces of the fibration.
