## Main Question or Discussion Point

given a partition function

[tex] Tr[e^{-BH}] [/tex] or [tex] Z(B)= \int_{P}dx dp e^{-BH(p,q)} [/tex]

is there any meaning for its zeros ? , i mean what happens in case the partition function Z(B)=0 for some 'B' or temperature [tex] B=1/kT [/tex] do these zeros have a meaning ?? thanks
