Self-similar solutions with fat tails for a coagulation equation with nonlocal drift
[Solutions auto-similaires à décroissance lente pour une équation de coagulation avec transport non local]
Comptes Rendus. Mathématique, Volume 347 (2009) no. 15-16, pp. 909-914.

L'existence de solutions auto-similaires préservant le volume total est établie pour une équation de coagulation incluant un terme de transport non local. Bien que cette équation admette des profils auto-similaires décroissant exponentiellement à l'infini, des profils auto-similaires avec une décroissance algébrique à l'infini sont construits lorsque le volume total est suffisamment petit.

We investigate the existence of self-similar solutions for a coagulation equation with nonlocal drift. In addition to explicitly given exponentially decaying solutions we establish the existence of self-similar profiles with algebraic decay.
