Coagulation‐Fragmentation Equations with Multiplicative Coagulation Kernel and Constant Fragmentation Kernel

We study a critical case of coagulation-fragmentation equations with multiplicative coagulation kernel and constant fragmentation kernel. Our method is based on the viscosity solutions to new singular Hamilton-Jacobi equation, which results from applying Bernstein transform original equation. include well-posedness, regularity, long-time behaviors equation in certain regimes, have implications well-posedness mass-conserving © 2021 Wiley Periodicals LLC.
