Some Landau–Kolmogorov Type Inequalities for Differential Operators Generated by Polynomials

Studia Scientiarum Mathematicarum Hungarica, 2021
In this paper, we establish some Landau–Kolmogorov type inequalities for differential operators generated by polynomials in the following formfor all , where 0 < g ≤ p ≤ ∞, and the differential operator P (D) is obtained from the polynomial P (x) by substituting . Moreover, the explicit form of and are given.

Multivariate Landau–Kolmogorov-type inequality

Mathematical Proceedings of the Cambridge Philosophical Society, 1989
AbstractAssuming that the nth iterate of the Laplacian Δnf belongs to L∞(ℝ), we show for 0 < k < 2n thatwhere ∂/∂ξi is the derivative in the ei direction. The result is also extended to other Banach spaces of functions on ℝd.
