当条件事件被置于未来时间u<t或中间时间u<t时,我们给出了[0,t]中布朗桥最大值分布的一些扩展。作为极限情况,得到了布朗运动和布朗桥的标准分布。这些结果也使我们能够推导出布朗桥的首次通过时间的分布。对具有漂移μ的布朗桥进行了类似的推广;在这种情况下,证明了最大分布与μ(当u≥t)无关。最后,考虑了在[0,t]中,当b (u)=η(对于>t和u<t)时,布朗运动的双面极大分布的情况。
We present some extensions of the distributions of the maximum of the Brownian bridge in [0,t] when the conditioning event is placed at a future timeu>t or at an intermediate timeu<t. The standard distributions of Brownian motion and Brownian bridge are obtained as limiting cases. These results permit us to derive also the distribution of the first-passage time of the Brownian bridge. Similar generalizations are carried out for the Brownian bridge with drift μ; in this case, it is shown that the maximal distribution is independent of μ (whenu≥t). Finally, the case of the two-sided maximal distribution of Brownian motion in [0,t], conditioned onB(u)=η (for bothu>t andu<t), is considered.
