The a.thors study the la.ge time a.ymptotics of a.solution of the Fisher-KPP rea.tion-diffusion equa.ion, with a. initia. condition tha. is a.compa.t perturba.ion of a.step function. a.well-known result of Bra.son sta.es tha., in the reference fra.e moving a. 2t-(3/2 )log t+x∞, the solution of the equa.ion converges a. t → +∞ to a.tra.sla.e of the tra.eling wa.e corresponding to the minima. speed c_* = 2. The consta.t x∞ depends on the initia. condition u(0, x). The proof is ela.ora.e, a.d ba.ed on proba.ilistic *** purpose of this pa.er is to provide a.simple proof ba.ed on PDE a.guments.
