摘要
Rates of decay for the total mass of the solutions to Smoluchovski's equation with homogeneous kernels of degree; > are proved. That implies that gelation always occurs. Morrey estimates from below and from above on solutions around the gelation time are also obtained which are in agreement with previously known formal results on the profile of solutions at gelling time. The same techniques are applied to the coagulation-fragmentation model for which gelation is established in some particular cases.
