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.

A Quadratic Mean Field Games Model for the Langevin Equation

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 ...

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.

Optimal inequalities for bounding Toader mean by arithmetic and quadratic means

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we present the best possible parameters α ( r ) $\alpha(r)$ and β ( r ) $\beta(r)$ such that the double inequality [ α ( r ) A r ( a , b ) + ( 1 − α ( r ) ) Q r ( a , b ) ] 1 / r < T D [ A ( a , b ) , Q ( a , b ) ] < [ β ( r ) A r ( a , b )

Optimal power mean bounds for the second Yang mean

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we present the best possible parameters p and q such that the double inequality M p ( a , b ) < V ( a , b ) < M q ( a , b ) $$ M_{p}(a,b)< V(a,b)< M_{q}(a,b) $$ holds for all a , b > 0 $a, b>0$ with a ≠ b $a\neq b$ , where M r ( a , b ) = [

Optimal bounds for two Sándor-type means in terms of power means

open access: yesJournal of Inequalities and Applications, 2016
In the article, we prove that the double inequalities M α ( a , b ) < S Q A ( a , b ) < M β ( a , b ) $M_{\alpha }(a,b)< S_{QA}(a,b)< M_{\beta}(a,b)$ and M λ ( a , b ) < S A Q ( a , b ) < M μ ( a , b ) $M_{\lambda }(a,b)< S_{AQ}(a,b)< M_{\mu}(a,b)$ hold ...

Optimal two-parameter geometric and arithmetic mean bounds for the Sándor–Yang mean

open access: yesJournal of Inequalities and Applications, 2019
In the article, we provide the sharp bounds for the Sándor–Yang mean in terms of certain families of the two-parameter geometric and arithmetic mean and the one-parameter geometric and harmonic means.

Comparative Study on Main Crop Yield Separation Methods

open access: yes应用气象学报, 2020
Crop yield separation is one of the important steps in analyzing the impact of meteorological factors on yield. Statistical rice yield data for 1985-2018 from 24 counties in Jiangsu are used to analyze the rationality of different separation methods. Six

Linear-Quadratic $N$-person and Mean-Field Games with Ergodic Cost [PDF]

open access: yes, 2014
We consider stochastic differential games with $N$ players, linear-Gaussian dynamics in arbitrary state-space dimension, and long-time-average cost with quadratic running cost. Admissible controls are feedbacks for which the system is ergodic.
