Three random variable transformations giving Heisenberg-type uncertainty relations

open access: yes
Though intrinsically probabilistic, the 1927 quantum mechanics Heisenberg uncertainty relation is still non-existent as a native Kolmogorov probability construct. This paper fills the gap via three random variable transformations that generate Heisenberg-

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

open access: yesStudia 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.

Pointwise Inequalities of Landau–Kolmogorov Type for Functions Defined on a Finite Segment

open access: yesUkrainian Mathematical Journal, 2001
For arbitrary \(t\in [0,1]\), \(p\in [1,\infty ]\) and \(A\geq 2\) the author finds the best possible constant \(B\) in the inequality \[ |x'(t)|\leq A\|x\|_{L_\infty [0,1]}+B\|x''\|_{L_p(0,1)}. \] This leads to the precise inequality for the norms \[ \|x'\|_\infty \leq \frac{2}{h}\|x\|_\infty +\left( \frac{h}{p'+1}\right)^{1/p'}\|x''\|_p \] valid for ...

Equivalence of the Local Markov Inequality and a Kolmogorov Type Inequality in the Complex Plane

open access: yesPotential Analysis, 2012
We prove that a compact subset of the complex plane satisfies a local Markov inequality if and only if it satisfies a Kolmogorov type inequality. This result generalizes a theorem established by Bos and Milman in the real case.

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.

On Inequalities of the Landau–Kolmogorov–Hörmander Type on a Segment and Real Straight Line

Ukrainian Mathematical Journal, 2000
We prove inequalities of the Landau–Kolmogorov–Hormander type for the uniform norms (on some subinterval) of positive and negative parts of intermediate derivatives of functions defined on a finite interval. By using the limit transition, we obtain a new proof or the well-known Hormander result.
