it is claimed that absolute summability is equivalent to the p152
definition of the ROC being the "set where X(z) attains a finite value."
these are not equivalent, since x[n] = (1/n) u[n-1] is not absolutely
summable, yet X(z) has a finite value for z=-1.

5.2.31 looks different than 4.3.37 only because the order of terms differs.
