Finite–N scaling, gelation cutoff, and matched asymptotics for Smoluchowski coagulation equation
Abstract We develop a finite-N matched-asymptotic theory for Smoluchowski coagulation. Starting from the infinite system of ODEs, we use conservation laws to obtain closed scalar evolution equations for suitable moments. For the constant kernel a j , k = K $a_{j,k}=K$ , this leads to an exact…
