A note on Bernstein and Markov type inequalities

Journal of Approximation Theory, 2005
Let \(\mathcal P_n\) denote the set of all polynomials of degree at most \(n\). By the well-known result of Duffin and Schaeffer, for every \(p\in\mathcal P_n\) one has \[ \| p^\prime\| _{[-1,1]}\leq n^2\max_{0\leq j\leq n}| p(\cos(j\pi/n)| , \] which is a discrete refinement of the famous Markov inequality \[ \| p^\prime\| _{[-1,1]}\leq n^2\| p\| _ ...

Large parameter asymptotic analysis for homogeneous normalized random measures with independent increments

Canadian Journal of Statistics, EarlyView.
Abstract Homogeneous normalized random measures with independent increments represent a broad class of Bayesian nonparametric priors and thus are widely used. In this article, we obtain the strong law of large numbers, the central limit theorem (CLT), and the functional central limit theorem (fCLT) of such measures when the concentration parameter a ...

Lupaş-type inequality and applications to Markov-type inequalities in weighted Sobolev spaces

Bulletin of Mathematical Sciences, 2021
Weighted Sobolev spaces play a main role in the study of Sobolev orthogonal polynomials. In particular, analytic properties of such polynomials have been extensively studied, mainly focused on their asymptotic behavior and the location of their zeros. On

Variance bounding and geometric ergodicity of Markov chain Monte Carlo kernels for approximate Bayesian computation [PDF]

, 2014
Approximate Bayesian computation has emerged as a standard computational tool when dealing with intractable likelihood functions in Bayesian inference. We show that many common Markov chain Monte Carlo kernels used to facilitate inference in this setting

Legacy effects of redlining on the distribution of greenspaces in US cities

Frontiers in Ecology and the Environment, EarlyView.
We investigated how a discriminatory housing policy—redlining—has shaped the spatial patterns and configurations of greenspaces throughout 177 cities in the contiguous US. Housing segregation has been a long‐term development practice that has sequestered communities of color to areas with elevated environmental and public health risks.

Equivalence of Markov's and Schur's inequalities on compact subsets of the complex plane

Journal of Inequalities and Applications, 1999
We prove that, on an arbitrary compact subset of the complex plane, Markov's and Schur's inequalities are equivalent.

Small sets and Markov transition densities [PDF]

, 2002
The theory of general state-space Markov chains can be strongly related to the case of discrete state-space by use of the notion of small sets and associated minorization conditions. The general theory shows that small sets exist for all Markov chains on

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting

Journal of Forecasting, EarlyView.
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.
