Turán type converse Markov inequalities in $L^q$ on a generalized Erőd class of convex domains

Polina Yu. Glazyrina, Szilárd Gy. Révész

P. Turán was the first to derive lower estimations on the uniform norm of the derivatives of polynomials $p$ of uniform norm $1$ on the interval I:=[-1,1] and the disk D:=$\{z \in…
