Mass-conserving solutions to coagulation-fragmentation equations with non-integrable fragment distribution function (1804.08861v1)
Published 24 Apr 2018 in math.AP, math-ph, and math.MP
Abstract: Existence of mass-conserving weak solutions to the coagulation-fragmentation equation is established when the fragmentation mechanism produces an infinite number of fragments after splitting. The coagulation kernel is assumed to increase at most linearly for large sizes and no assumption is made on the growth of the overall fragmentation rate for large sizes. However, they are both required to vanish for small sizes at a rate which is prescribed by the (non-integrable) singularity of the fragment distribution.
