KW - Pál type interpolation, non-uniformly distributed set of points on unit circle, Legendre polynomials.
AB - <p style="text-align: justify;">In this paper we study the problem of explicit representation and convergence
of Pál type (0;1) interpolation and its converse, with some additional conditions,
on the non-uniformly distributed nodes on the unit circle obtained by projecting the
interlaced zeros of $P_n(x)$ and $P′_n(x)$ on the unit circle. The motivation to this problem
can be traced to the recent studies on the regularity of Birkhoff interpolation and Pál
type interpolations on non-uniformly distributed zeros on the unit circle.</p>
