. Convergence of a family of Markov jump processes evolving accordingto coagulation-fragmentation dynamics to the corresponding deterministicequations is proved on every finite interval of existence. After obtaininglocal existence by the Banach fixed-point theorem, we can prove global existenceusing the positivity of the limit function on the local existence interval.0. IntroductionThe so-called Smoluchowski equations (coagulation-fragmentation equations):ddtu1(t) = Gammau11...
