讲座主题:Refracted ocsilating Brownian motion
摘要:
Motivated by problems in stochastic control, we consider the unique solution
to the following SDE

for
and 
For
an explicit expression for transition density of
was obtained by Keilson and Wellner (1978). For
the transition density was obtained by Karatzas and Shreve (1984). But the transition density for general
was not known.
We first solve the exit problem to process
, and then adopt a perturbation approach to find an expression of potential measure for
. The transition density is found by inverting the Laplace transform. We will also mention its application in risk models. (This talk is based on joint work with Zengjing Chen, Panyu Wu and Weihai Zhang.)
