Short-time heat flow and functions of bounded variation in \mathbf{R}^N

On prouve une caracterisation des ensembles avec perimetre fini et des fonctions a variation bornee en termes du comportement du semi-groupe de la chaleur dans R N au voisinage de t = 0. On prouve aussi un resultat plus precis pour les ensembles avec frontiere assez reguliere.
