关于电报过程的条件概率的一个注记

A Note on the Conditional Probabilities of the Telegraph Process

Fabrizio Cinque

摘要:

我们考虑具有两个速度$a_1>a_2\in\mathbb{R}$和两个反转率$λ_1,λ_2>0$的电报过程。我们研究了它的一些功能方面的条件概率措施的初始速度和数量的变化的方向是已知的。我们展示了一个新的证明(条件)概率法的诱导和详细的研究在时间$t>0$条件下,其位置在以前的时间$0<s<t$的运动分布。在对称过程的情况下,我们提出了一些结果的联合分布的位置的运动在时间$t>0$,其最大值和最小值的时刻。

英文摘要:

We consider the telegraph process with two velocities, $a_1>a_2\in\mathbb{R}$, and two rates of reversal, $λ_1,λ_2>0$. We study some of its features with respect to the conditional probability measure where both the initial speed and the number of changes of direction are known. We exhibit a new proof by induction of the (conditional) probability law and a detailed study of the distribution of the motion at time $t>0$ conditioned on its position at a previous time $0<s<t$. In the case of a symmetric process, we present some results on the joint distribution of the position of the motion at time $t>0$, its maximum and its minimum up to that moment.
