Parabolic Regularity of Spectral Functions [PDF]

open access: yesMathematics of Operations Research, 2023
This paper is devoted to the study of the second-order variational analysis of spectral functions. It is well-known that spectral functions can be expressed as a composite function of symmetric functions and eigenvalue functions.

Twice epi-differentiablity and parabolic regularity of a class of non-amenable functions [PDF]

open access: yesOptimization, 2022
This paper concerns the twice epi-differentiability and parabolic regularity of a class of non-amenable functions, the composition of a piecewise twice differentiable (PWTD) function and a parabolically semidifferentiable mapping.

A simple proof of second-order sufficient optimality conditions in nonlinear semidefinite optimization [PDF]

open access: yesOptimization Letters, 2022
In this note, we present an elementary proof for a well-known second-order sufficient optimality condition in nonlinear semidefinite optimization which does not rely on the enhanced theory of second-order tangents.

Climate Model Code Genealogy and Its Relation to Climate Feedbacks and Sensitivity

open access: yesJournal of Advances in Modeling Earth Systems, Volume 15, Issue 7, July 2023., 2023
Abstract Contemporary general circulation models (GCMs) and Earth system models (ESMs) are developed by a large number of modeling groups globally. They use a wide range of representations of physical processes, allowing for structural (code) uncertainty to be partially quantified with multi‐model ensembles (MMEs).

Mathematical Modeling of Real‐Time Systems Using Heun and Piecewise Methods

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
It is often said that mathematical modeling is an implementation of mathematics in real‐world problems with the aim of better understanding them, so we can say that mathematical modeling is linked to the solution of problems. Some of the essential principles and procedures of mathematical modeling are discussed using formulas and equations.

Communication‐Efficient Modeling with Penalized Quantile Regression for Distributed Data

open access: yesComplexity, Volume 2021, Issue 1, 2021., 2021
In order to deal with high‐dimensional distributed data, this article develops a novel and communication‐efficient approach for sparse and high‐dimensional data with the penalized quantile regression. In each round, the proposed method only requires the master machine to deal with a sparse penalized quantile regression which could be realized fastly by

Dưới vi phân parabolic và áp dụng vào nghiên cứu điều kiện tối ưu

open access: yesDong Thap University Journal of Science, 2023
In this paper, we introduce the notion of parabolic subdifferential of funtions through their parabolic subderivative. Besides, we present some properties of parabolic subdifferential and applications of parabolic subdifferential to necessary optimality ...

Bouligand–Landweber iteration for a non-smooth ill-posed problem [PDF]

open access: yesNumerische Mathematik, 2018
This work is concerned with the iterative regularization of a non-smooth nonlinear ill-posed problem where the forward mapping is merely directionally but not Gâteaux differentiable.

Robust scoring rules

open access: yesTheoretical Economics, Volume 15, Issue 3, Page 955-987, July 2020., 2020
Is it possible to guarantee that the mere exposure of a subject to a belief elicitation task will not affect the very same beliefs that we are trying to elicit? In this paper, we introduce mechanisms that make it simultaneously strictly dominant for the subject (a) not to acquire any information that could potentially lead to belief updating as a ...

A generalization of arithmetic derivative to p-adic fields and number fields [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The arithmetic derivative is a function from the natural numbers to itself that sends all prime numbers to 1 and satisfies the Leibniz rule. The arithmetic partial derivative with respect to a prime p is the p-th component of the arithmetic derivative ...
