Randomized and Exchangeable Improvements of Markov's, Chebyshev's and Chernoff's Inequalities [PDF]

open access: yes, 2023
We present simple randomized and exchangeable improvements of Markov's inequality, as well as Chebyshev's inequality and Chernoff bounds. Our variants are never worse and typically strictly more powerful than the original inequalities.

A safe reinforcement learning approach for autonomous navigation of mobile robots in dynamic environments

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.

Best exponents in Markov's inequalities [PDF]

open access: yes, 2014
By means of weakly equilibrium Cantor-type sets, solutions of two problems related to polynomial inequalities are presented: the problem by M. Baran et al. about a compact set K ⊂ double-struck C such that the Markov inequality is not valid on K with the

Optimal factors in Vladimir Markov's inequality in L2 norm [PDF]

open access: yes, 2018
In this paper we discuss a problem of computation of constants in Vladimir Markov's type inequality in L2 norm on the interval [-1, 1]

Markov's weak inequality for algebraic polynomials on a closed interval [PDF]

open access: yes, 2019
For a real algebraic polynomial Pn of degree n, we consider the ratio Mn(Pn) of the measure of the set of points from [-1, 1] where the absolute value of the derivative exceeds n2 to the measure of the set of points where the absolute value of the ...

On grid diagrams, braids and Markov moves [PDF]

open access: yes, 2010
Includes abstract.Includes bibliographical references (leaves 42).Grid diagrams are essential in the new combinatorial version [MOST07] of the Heegaard Floer knot homology, and proving that these homologies are actually knot and link invariants depends ...

Markov's inequality and the existence of an extension operator for C∞ functions [PDF]

open access: yes, 1990
It is shown that if E is a C∞ determining compact set in Rn, then Markov's inequality for derivatives of polynomials holds on E iff there exists a continuous linear extension operator L:C∞(E)→C∞(Rn).

Markov's theorem in 3-manifolds [PDF]

open access: yes, 1997
In this paper we first give a one-move version of Markov's braid theorem for knot isotopy in S3 that sharpens the classical theorem. Then we give a relative version of Markov's theorem concerning a fixed braided portion in the knot.

A proof of Markov's theorem for polynomials on Banach spaces [PDF]

open access: yes, 2010
Our object is to present an independent proof of the extension of V.A. Markov's theorem to Gâteaux derivatives of arbitrary order for continuous polynomials on any real normed linear space.
