A collection of spherical obstacles in the unit ball in Euclidean space is said to be avoidable for Brownian motion if there is a positive probability that Brownian motion diffusing from some point in the ball will avoid all the obstacles and reach the boundary of the ball. The centres of the spherical obstacles are generated according to a Poisson point process while the radius of an obstacle is a deterministic function. If avoidable con gurations are generated with positive probability Lundh calls this percolation di usion. An integral condition for percolation di ffusion is derived in terms of the intensity of the point process and the function that determines the radii of the obstacles. info:eu-repo/semantics/openAccess L'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative Commons: http://creativecommons.org/licenses/by-nc-nd/3.0/es/ Percolació (Física estadística) Difusió info:eu-repo/semantics/preprint O'Donovan, Julie Ortega Cerdà, Joaquim Centre de Recerca Matemàtica Prepublicacions del Centre de Recerca Matemàtica ; 1026 11 191988 http://ddd.uab.cat/pub/prepub/2011/hdl_2072_179356/Pr1026.pdf Adreça alternativa http://hdl.handle.net/2072/179356 PREPUB UAB DDD id 86227 filename Pr1026.pdf file 0 MD5 2ab4eb3c7d7b9095f62d877301187fce 191988 PDF 1.4 filepath pub/prepub/2011/hdl_2072_179356/Pr1026.pdf disk
