what is Lee-Yang circle theorem and what is it used for ?? , i mean given a measure how can you know that is Ferromagnetic and hence all its zeros lie on a Circle ??
the Lee-Yang circle theorem proof is it only valid for the measure $ \delta (x-1) + \delta (x+1) $
how can you proof the Circle theorem for any measure ?? if any measure is positive and EVEN does Lee-Yang circle theorem hold ??
