Tangential Markov inequalities on singular varieties L. BosPierre Milman 41A1714J17Markov inequalityalgebraic varietyresolution of singularities We show that an algebraic variety in $mathbb{R}^n$ admits a tangential Markov inequality (for the derivatives of polynomials) of an exponent depending on the nature of the singularities of the variety.
