“…Our symmetry concept has been extended in many directions to obtain other applications, such as the jointly self-dual concept introduced by Molchanov and Schmutz (2010) to obtain a multivariate version of the PCS, while the self-dual concept is analogous to ours. Now, since the OU-SV process is not necessarily a Lévy process, 3 to address its symmetry property, we need to obtain the triplet characteristic of the dual process X , which we denote by = (B X , C X , ν X ), from the characteristic triple = (B X , C X , ν X ) of the original process X .…”
