Limit theorems for conditioned multitype Dawson-Watanabe processes and Feller diffusions (2008)

Champagnat, Nicolas; INRIA, France; Nicolas.champagnat@sophia.inria.fr, Roelly, Sylvie; Potsdam University, Germany; Roelly@math.uni-potsdam.de

A multitype Dawson-Watanabe process is conditioned, in subcritical and critical cases, on non-extinction in the remote future. On every finite time interval, its distribution is absolutely continuous...
