| Abstract: |
| In this paper, we investigate functional limit for Lévy's modulus of continuity of a fractional Brownian motion. By using large deviation and small deviation for Brownian motion, a liminf for Lévy's modulus of continuity of a fractional Brownian motion is obtained, which extends the corresponding result of Brownian motion. |
