Limit elements in the configuration algebra for a cancellative monoid    [PDF]

Kyoji Saito

We introduce two spaces $\Omega(\Gamma,G)$ and $\Omega(P_{\Gamma,G})$ of
pre-partition functions and of opposite series, respectively, which are
associated with a Cayley graph $(\Gamma,G)$ of a cancellative monoid $\Gamma$
with a finite generating system $G$ and with its growth function
$P_{\Gamma,G}(t)$. Under mild assumptions on $(\Gamma,G)$, we introduce a
fibration $\pi_\Omega:\Omega(\Gamma,G)\to \Omega(P_{\Gamma,G})$ equivariant
with a $\Z_{\ge0}$-action, which is transitive if it is of finite order. Then,
the sum of pre-partition functions in a fiber is a linear combination of
residues of the proportion of two growth functions $P_{\Gamma,G}(t)$ and
$P_{\Gamma,G}\mathcal{M}(t)$ attached to $(\Gamma,G)$ at the places of poles on
the circle of the convergent radius.
