probability transition function


A probability transition function (p.t.f., or just t.f. in context) on a measurable spaceMathworldPlanetmathPlanetmath (Ω,) is a family Ps,t, 0s<t of transition probabilities on (Ω,) such that for every three real numbers s<t<v, the family the Chapman-Kolmogorov equation

Ps,t(x,dy)Pt,v(y,A)=Ps,v(x,A)

for every xΩ and A. The t.f. is said to be if Ps,t depends on s and t only through their t-s. In this case, we write Pt,0=Pt and the family {Pt,t0} is a semigroup, and the Chapman-Kolmogorov equation reads

Pt+s(x,A)=Ps(x,dy)Pt(y,A).
