On asymptotic independence of the exit moment and position from a small domain for diffusion processes

Vitalii Gasanenko (2003)

Open Mathematics

Similarity:

If ξ(t) is the solution of homogeneous SDE in R m, and T ∃ is the first exit moment of the process from a small domain D ∃, then the total expansion for the following functional showing independence of the exit time and exit place is E e x p ( - λ T ε ) f ( ξ ( T ε ) ε ) - E e x p ( - λ T ε ) E f ( ξ ( T ε ) ε ) , ε ↘ 0 , λ > 0 .
