Abstract
dc.description.abstract
Let (Xt ) be a one dimensional diffusion corresponding to the operator L=
1
2 xx&: x , starting from x>0 and T0 be the hitting time of 0. Consider the
family of positive solutions of the equation L =&* with * # (0, '), where
'=&limt (1 t) log Px(T0>t). We show that the distribution of the h-process
induced by any such is limM Px(X # A | SM<T0), for a suitable sequence
of stopping times (SM :M 0) related to which converges to with M. We
also give analytical conditions for '=*
, where*
is the smallest point of increase
of the spectral measure associated to L*.
