摘要：
On compact sets preserving Markov's inequality, Bernstein-type conditions for a continuous function to be of class Ck are discussed. Also, relationships between the distribution of zeros of polynomials of best uniform or Lp approximation to a given function and its differential properties are established. © 1991.
