Inequalities of Hermite-Hadamard Type [PDF]

Moroccan Journal of Pure and Applied Analysis, 2015
AbstractSome inequalities of Hermite-Hadamard type for λ-convex functions defined on convex subsets in real or complex linear spaces are given. Applications for norm inequalities are provided as well.

Penalized Convex Estimation in Dynamic Location Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper studies L1$$ {L}^1 $$‐penalized estimation for location models yt=mt+ϵt$$ {y}_t={m}_t+{\epsilon}_t $$, where mt$$ {m}_t $$ is defined by a possibly non‐Markovian recursion and ϵt$$ {\epsilon}_t $$ is a martingale difference sequence with possibly time‐varying conditional variance.

Old and New on the Hermite-Hadamard Inequality

Real Analysis Exchange, 2004
This paper is a survey of the results grown up from the Hermite-Hadamard inequality. Both, old and new results are presented, complemented and discussed within this framework. The Hermite-Hadamard inequality is presented in connection with subdifferentials and quadrature formulae; some improvements of it are discussed. Then a short account on classical

Optimal Portfolio Choice With Cross‐Impact Propagators

Mathematical Finance, EarlyView.
ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...

Probing and Graph Coloring Techniques for Trace Estimation in Lattice QCD

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The computation of Tr[D−1]$\mathrm{Tr}[D^{-1}]$, where D$D$ is the Wilson–Dirac matrix of Lattice QCD, is a fundamental and computationally demanding task with applications to disconnected hadronic correlation functions. Since D−1$D^{-1}$ is a dense matrix of prohibitive size, its trace cannot be computed exactly, and one must resort to ...

Convergence in Distribution of the P–P Process in L1[0,1]$$ {\boldsymbol{L}}^{\mathbf{1}}\left[\mathbf{0},\mathbf{1}\right] $$

Stat, Volume 15, Issue 4, December 2026.
ABSTRACT We show that the percentile–percentile (P–P) process constructed from an independent and identically distributed sample of pairs converges in distribution in L1[0,1]$$ {L}^1\left[0,1\right] $$ if and only if the associated P–P curve is absolutely continuous.

Partitioned and Hadamard product matrix inequalities [PDF]

Journal of Research of the National Bureau of Standards, 1978
This note is partly expositor). Inequalities relating inversion with, respectively, extraction of principal submatriees and the Hadamard product in the two possible orders are developed in a simple and unified way for positive definite matrices. These inequalities are known, hut we also characterize the cases of equality and strict inequality.

A Note on Local Polynomial Regression for Time Series in Banach Spaces

Journal of Time Series Analysis, Volume 47, Issue 6, Page 1124-1138, November 2026.
ABSTRACT This work extends local polynomial regression to Banach space‐valued time series for estimating smoothly varying means and their derivatives in non‐stationary data. The asymptotic properties of both the standard and bias‐reduced Jackknife estimators are analyzed under mild moment conditions, establishing their convergence rates.

On Hermite-Hadamard Type Inequalities for s-Convex Functions on the Coordinates via Riemann-Liouville Fractional Integrals

Journal of Applied Mathematics, 2014
We obtain some Hermite-Hadamard type inequalities for s-convex functions on the coordinates via Riemann-Liouville integrals. Some integral inequalities with the right-hand side of the fractional Hermite-Hadamard type inequality are also established.
