Abstract: |
In this paper, we study the collision local time of two independent (N,d)-bifractional Brownian motions BH1,K1 and BH2,K2 . Using the Fourier analysis, existence and joint continuity for the collision local time are obtained. The problem of the collision local time of fractional Brownian motion is generalized. |
