document: Regularity of some ` incomplete ' Pal-type interpolation problems In this paper the regularity of nine Pal-type interpolation problems is proved . In the literature interpolation on the zeros of the pair W/sub n / / sup -LRB- alpha -RRB- / -LRB- z -RRB- = -LRB- z + alpha -RRB- / sup n / + -LRB- 1 + alpha z -RRB- / sup n / , v/sub n / / sup -LRB- alpha -RRB- / -LRB- z -RRB- = -LRB- z + alpha -RRB- / sup n / - -LRB- 1 + alpha z -RRB- / sup n / with 0 < alpha < 1 has been studied . Here the nodes form a subset of these sets of zeros
