Abstract:
We present a proof of the existence of solutions to the continuous coagulation equation with multiple fragmentation whenever ther kernels satisfy certain growth conditions. The proof relies on weak L^1 compactness methods applied to suitably chosen approximating equations. The question of uniqueness is also considered. The result is an extension of previous result of Lamb [15] that covers somer kernels modeling particles in flows that were not included in the previous results.
