Query: A note on mass-conserving solutions to the coagulation-fragmentation
  equation by using non-conservative approximation   In general, the non-conservative approximation of coagulation-fragmentation
equations (CFEs) may lead to the occurrence of gelation phenomenon. In this
article, it is shown that the non-conservative approximation of CFEs can also
provide the existence of mass conserving solutions to CFEs for large classes of
unbounded coagulation and fragmentation kernels.
