I know that the random walk on Z is transient or recurrent depending upon the probability. Now I think that the random walk on Z+ is also null recurrent or non-null recurrent or transient(probability of transition from i to i+1 is p and i+1 to i is q and from 0 to 0 is q, 0 to 1 is p where p+q=1, i>=0) depending on p. But I can't approach for the proper proof. please Help me. Thanks in advance.
