Analytic Fragmentation Semigroups and Classical Solutions to Coagulation-fragmentation Equations - a Survey

In the paper we present a survey of recent results obtained by the author that concern discrete fragmentation.coagulation models with growth. Models like that are particularly important in mathematical biology and ecology where they describe the aggregation of living organisms. The main results discussed in the paper are the existence of classical semigroup solutions to the fragmentation.coagulation equations.
