Description : This video illustrates the study by E. Bernard, M. Doumic and P. Gabriel https://hal.archives-ouvertes.fr/hal-01363549/document by showing the time behaviour of the solution to the following growth-fragmentation equation: $\frac{\partial}{\partial t} u(t,x) + \frac{\partial}{\partial t} (x u(t,x)) + B(x)u(t,x)=4B(2x)u(t,2x),\qquad u(0,x)=u^{in}(x).$ The numerical scheme is explicit, and uses a splitting between the transport operator and the fragmentation operator, on a geometric grid. This allows to capture the asymptotic periodic behaviour (due to a lack of dissipativity in the equation).
