Smoothness of moments of the solutions of discrete coagulation equations with diffusion

Research output: Contribution to journalArticlepeer-review

Abstract

In this paper, we establish smoothness of moments of the solutions of discrete coagulation-diffusion systems. As key assumptions, we suppose that the coagulation coefficients grow at most sub-linearly and that the diffusion coefficients converge towards a strictly positive limit (those conditions also imply the existence of global weak solutions and the absence of gelation).
