Instantaneous gelation and nonexistence for the Oort-Hulst-Safronov coagulation model
Pooja Rai, Ankik Kumar Giri, Volker John
The possible occurrence of instantaneous gelation to Oort-Hulst-Safronov (OHS) coagulation equation is investigated for a certain class of unbounded coagulation kernels. The existe…

On the discrete Safronov-Dubovskii coagulation equation: well-posedness, mass-conservation and asymptotic behaviour
Mashkoor Ali, Pooja Rai, Ankik Kumar Giri
The global existence of mass-conserving weak solutions to the Safronov-Dubovskii coagulation equation is shown for the coagulation kernels satisfying the at most linear growth for…

Mass-conserving weak solutions to Oort-Hulst-Safronov coagulation equation with singular rates
Prasanta Kumar Barik, Pooja Rai, Ankik Kumar Giri
Existence of global weak solutions to the continuous Oort-Hulst-Safronov (OHS) coagulation equation is investigated for coagulation kernels capturing a singularity near zero and gr…
