[Integration par parties sur Ponts de Bessel et EDPS correspondantes]
Nous prouvons des formules d'intégration par parties par rapport à la loi des Ponts de Bessel de dimension δ⩾3. Remarquons que dans le cas δ=3 nous obtenons une mesure de bord infini-dimensionelle, et pour δ>3 une dérivée logarithmique singulière. Nous donnerons aussi des applications à des EDPS avec bruit blanc en espace-temps et termes de dérive singuliers, dont les solutions sont non-négatives.
We prove integration by parts formulae with respect to the law of Bessel Bridges of dimension δ⩾3. For δ=3 we have an infinite-dimensional boundary measure, and for δ>3 a singular logarithmic derivative. We give applications to SPDEs with additive space-time white noise and singular drifts, whose solutions are non-negative.
