Markov inequality on sets with polynomial parametrization

The main result of this paper is the following: if a compact subset E of ℝ n is UPC in the direction of a vector v ∈ S n - 1 then E has the Markov property in the direction of v. We present a method which permits us to generalize as well as to improve an earlier result of Pawłucki and Pleśniak [PP1].

Polynomial inequalities on algebraic sets

We give an estimate of Siciak’s extremal function for compact subsets of algebraic varieties in ℂ n (resp. ℝ n ). As an application we obtain Bernstein-Walsh and tangential Markov type inequalities for (the traces of) polynomials on algebraic sets.
