对偶过程的时间变换 ON TIME CHANGES OF DUAL PROCESSES 昌志华 Chang Zhihua 1 first-author 武汉大学数学系 武汉大学数学系 Department of Mathematics,Wuhan University Department of Mathematics,Wuhan University 证明了相伴于拟正则狄氏型的对偶过程关于对偶可加泛函的时间变换，在一定条件下仍为对偶过程，且它们相伴的狄氏型仍为拟正则的． We discuss the time changes of dual processes and the associated quasi-regulal Dirichlet form, and prove that under certain conditions the dual-invariance of the processes and the quasi-regular invariance of the Dirichlet form hold under this time change. 拟正则狄氏型 对偶过程 光滑测度 可加泛函 时间变换 quasi-regular Dirichlet form dual processes smooth measure additive functional time change O211.62 1994-04-01 2021-04-01 4
