A Sharp Markov Brothers-Type Inequality in the Spaces $L_\infty$ and $L_1$ on the Segment
I. E. Simonov Institute of Mathematics and Computer Science, Ural Federal University, Ekaterinburg
Abstract:
The inequality between the uniform norm of the derivative of order $\ell$ of an algebraic polynomial of degree $n$ and the $L_1$-norm of the polynomial itself on a segment are studied. For all $\ell\ge(n-1)/3$, the exact constant and the extremal polynomial are written out.
Keywords:
Markov brothers' inequality, algebraic polynomial, trigonometric polynomial, Chebyshev polynomial, Legendre polynomial.
