WebIf p = 1 and d is non-empty, then clearly the random walk is not transient, because since you use the ℓ 1 norm, there is a closed surface which always reflects the walker back into the enclosed finite region. If, however, p = 0 then the walk is transient, since simple random walks in 3 dimensions are transient. WebThe persistent random walk model constitutes a well-established framework that can be easily augmented to incorporate extensions, such as cell reactions [27,28]. However, most existing methods and techniques for addressing the issue of persistent random walks with reactions focus on Markovian switching between two states [ 29 , 30 , 31 ].
