LARGE DEVIATION UPPER BOUND FOR THE LAW OF MATRIX-VALUED ORNSTEIN-UHLENBECK PROCESS |

Abstract: |
In this paper, we study the large deviation problem for the matrixvalued Ornstein Uhlenbeck processes. By constructing the exponedtial martingale, we obtain a large deviation upper bound for its empirical process, which extends the corresponding result for Hermitian Brownian motion. |
