Saddle-Point Equilibrium Strategy for Linear Quadratic Uncertain Stochastic Hybrid Differential Games Based on Subadditive Measures

Mathematics
This paper describes a kind of linear quadratic uncertain stochastic hybrid differential game system grounded in the framework of subadditive measures, in which the system dynamics are described by a hybrid differential equation with Wiener–Liu noise and

Explicit Characterization of Feedback Nash Equilibria for Indefinite, Linear-Quadratic, Mean-Field-Type Stochastic Zero-Sum Differential Games with Jump-Diffusion Models

Mathematics, 2020
We consider the indefinite, linear-quadratic, mean-field-type stochastic zero-sum differential game for jump-diffusion models (I-LQ-MF-SZSDG-JD).

Numerical Construction of Viable Sets for Autonomous Conflict Control Systems

Mathematics, 2014
A conflict control system with state constraints is under consideration. A method for finding viability kernels (the largest subsets of state constraints where the system can be confined) is proposed.

Repeated games for eikonal equations, integral curvature flows and non-linear parabolic integro-differential equations

, 2009
The main purpose of this paper is to approximate several non-local evolution equations by zero-sum repeated games in the spirit of the previous works of Kohn and the second author (2006 and 2009): general fully non-linear parabolic integro-differential ...

Collaborative defense model for crowdsensing networks based on incomplete Information differential games

Cybersecurity
Crowdsensing networks face complex security threats due to their open architecture and distributed collaboration model. However, existing defense methods neglect the heterogeneity of sensing nodes and information asymmetry between attackers and defenders,

On Linear Pursuit-Evasion Game Problems with GGr-Constraints on Controls of Players

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
This article investigates a differential game of pursuit-evasion for linear motion dynamics of two players, a pursuer and an evader. The pursuer’s control is subject to a geometric constraint (its Euclidean norm does not exceed a given constant α), while

Necessary and Sufficient Conditions for Pareto Optimality in Infinite Horizon Cooperative Differential Games [PDF]

In this article we derive necessary and sufficient conditions for the existence of Pareto optimal solutions for infinite horizon cooperative differential games. We consider games defined by non autonomous and discounted autonomous systems.
