A Quadratic Mean Field Games Model for the Langevin Equation [PDF]

open access: yesAxioms, 2021
We consider a Mean Field Games model where the dynamics of the agents is given by a controlled Langevin equation and the cost is quadratic. An appropriate change of variables transforms the Mean Field Games system into a system of two coupled kinetic Fokker–Planck equations.

Optimal inequalities for bounding Toader mean by arithmetic and quadratic means [PDF]

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we present the best possible parameters [Formula: see text] and [Formula: see text] such that the double inequality [Formula: see text] holds for all [Formula: see text] and [Formula: see text] with [Formula: see text], and we provide new bounds for the complete elliptic integral [Formula: see text] [Formula: see text] of the second kind,

Mean-field type quadratic BSDEs

open access: yesNumerical Algebra, Control and Optimization, 2023
In this paper, we give several new results on solvability of a quadratic BSDE whose generator depends also on the mean of both variables. First, we consider such a BSDE using John-Nirenberg's inequality for BMO martingales to estimate its contribution to the evolution of the first unknown variable.

Linear-Quadratic Mean Field Games [PDF]

open access: yesJournal of Optimization Theory and Applications, 2015
In this article, we provide a comprehensive study of the linear-quadratic mean field games via the adjoint equation approach; although the problem has been considered in the literature by Huang, Caines and Malhame (HCM, 2007a), their method is based on Dynamic Programming.

Backward-forward linear-quadratic mean-field Stackelberg games

open access: yesAdvances in Difference Equations, 2021
This paper studies a controlled backward-forward linear-quadratic-Gaussian (LQG) large population system in Stackelberg games. The leader agent is of backward state and follower agents are of forward state.

Alternative expressions for stand diameter in complex forests

open access: yesForest Ecosystems, 2023
Quadratic mean diameter is the most frequently reported descriptor of the diameter distribution of forests. As such, it is often used as an indicator of forest stand structure, developmental stage, and ecological and economic potential.

Quadratic Auto-Step Least Mean Square Equalization for High-Data-Rate IR-UWB Wireless Communication Systems

open access: yesIEEE Access, 2022
High-data-rate impulse radio ultra-wideband (IR-UWB) wireless communication system suffers from serious intersymbol interference (ISI) issues in an indoor multipath environment.

Quadratic means

open access: yesJournal of Mathematical Analysis and Applications, 2003
The paper considers expressions of the form \( {\mathfrak M} = f_1 \mp\sqrt{f_2}\) where \(f_1, f_2\), is a symmetric form of degree \(1, 2,\) in \(n\) variables. The case where \(f_1=0\) has been considered by the second author [Math. Inequal. Appl. 6, 581--593 (2003; Zbl 1047.26015)]. Using suitable bases for the two spaces of forms these expressions

Quadratic interpolation of the Heinz means [PDF]

open access: yesMathematical Inequalities & Applications, 2018
The main goal of this article is to present several quadratic refinements and reverses of the well known Heinz inequality, for numbers and matrices, where the refining term is a quadratic function in the mean parameters. The proposed idea introduces a new approach to these inequalities, where polynomial interpolation of the Heinz function plays a major
