Multi-dimensional BSDEs whose terminal values are bounded and have bounded Malliavin derivatives

Shiqi Song

We consider a class of multi-dimensional BSDEs on a finite time horizon (containing in particular Lipschitzian-quadratic BSDEs), whose terminal values are bounded as well as their…

Invariance properties in the dynamic gaussian copula model *

Stéphane Crépey, Shiqi Song

We prove that the default times (or any of their minima) in the dynamic Gaussian copula model of Cr{é}pey, Jeanblanc, and Wu (2013) are invariance times in the sense of Cr{é}pey an…

Invariance times

Stéphane Crépey, Shiqi Song

On a probability space we consider two filtrations and a stopping time such that the predi…

From Doob's maximal identity to Azema supermartingale

Shiqi Song

We characterize the random times whose Azema supermartingales take the form for some non negative local martingales starting from 1 vanishing at infinity,…

Construction of multi-default models with full viability

Shiqi Song

We study multi-default model which satisfies the quasi-left-continuity, the martingale representation property, the drift multiplier assumption and the full viability. We use $\nat…
