    random walk

    Hi,
    Is there a special term (or name) for a one dimensional random walk on the Naturals only? I mean a random walk that you start at a certain point on N and move right with probability p and left with probability 1-p and when you get to zero you must go right on the next turn?

    thanks!

    What about an (asymmetric) simple random walk on \mathbb{N} with reflection at 0?
