Resumen de On a Fokker-Planck equation arising in population dynamics

Mazen Saad, Thierry Goudon

• This paper is devoted to a Fokker-Planck equation arising in population dynamics. For general non negative initial data u0 Î L1 (W), we prove the existence of a weak non negative and mass-preserving solution belonging to Lq(0,T;W1,q (W)) for all 1 £ q < 4/3.
