“…In general, the degree of the numerator need not be the same as the degree of the denominator, but we limit our presentation to this case because it is sufficient for our purposes. This problem does not have a closed form solution, but it has been solved numerically for d = 1, ..., 14, by Cody, Meinardus and Varga [6], and subsequently up to degree d = 30 by Carpenter, Ruttan and Varga [5]. Interestingly, the problem does have a closed form solution if it is instead formulated (in the unit disk) over the extended approximation spacẽ…”
