1. Solutions to group problems gi,i-1=i? gii=-i(???) gi,i+1=i? Hence -gi,i+1/gii=???????=1-(-gi,i-1/gii). Thus the jump chain goes up one step with probability ????????and down one step with probability ?????????0 is an absorbing state. 2. Consider a 0-1 process. It has jump chain with transition matrix and stationary distribution (1/2,1/2), but the stationary distribution of the process itself is
