Query: On the possible temperatures for flows on an AF algebra   We exhibit a unital simple mono-tracial AF algebra A with the property that
for any compact set K of real numbers containing 0 there is a periodic flow on
A such the set of possible inverse temperatures for that flow is K, and for
each number in K the corresponding equilibrium state is unique.
