Rate of convergence to self-similarity for the fragmentation equation in L1 spaces
Résumé
In a recent result by the authors, it was proved that solutions of the self-similar fragmentation equation converge to equilibrium exponentially fast. This was done by showing a spectral gap in weighted $L^2$ spaces of the operator defining the time evolution. In the present work we prove that there is also a spectral gap in weighted $L^1$ spaces, thus extending exponential convergence to a larger set of initial conditions. The main tool is an extension result in arXiv : 1006.5523.
