Linear-quadratic Gaussian Games with Asymmetric Information: Belief Corrections Using the Opponents Actions

Ben Hambly, Renyuan Xu, Huining Yang

We consider two-player non-zero-sum linear-quadratic Gaussian games in which both players aim to minimize a quadratic cost function while controlling a linear and stochastic state…

Contagious McKean--Vlasov problems with common noise: from smooth to singular feedback through hitting times

Ben Hambly, Aldaïr Petronilia, Christoph Reisinger +2

We consider a family of McKean--Vlasov equations arising as the large particle limit of a system of interacting particles on the positive half-line with common noise and feedback.…

An SPDE with Robin-type boundary for a system of elastically killed diffusions on the positive half-line

Ben Hambly, Julian Meier, Andreas Sojmark

We consider a system of particles undergoing correlated diffusion with elastic boundary conditions on the half-line. By taking the large particle limit we establish existence and u…

McKean-Vlasov Equations with Positive Feedback through Elastic Stopping Times

Ben Hambly, Julian Meier

We prove existence and uniqueness of physical and minimal solutions to McKean-Vlasov equations with positive feedback through elastic stopping times. We do this by establishing a r…

A Stochastic Model of Chemorepulsion with Additive Noise and Nonlinear Sensitivity

Ilya Chevyrev, Ben Hambly, Avi Mayorcas

We consider a stochastic partial differential equation (SPDE) model for chemorepulsion, with non-linear sensitivity on the one-dimensional torus. We show that for any suitable init…
