seeks to move an economy from one level of capital to another, then the most efficient path …

Maximal -Regularity for Parabolic Hamilton–Jacobi Equations and Applications to Mean Field Games

M Cirant, A Goffi - Annals of PDE, 2021 - Springer
In this paper we investigate maximal L q-regularity for time-dependent viscous Hamilton–

Synchronization in a Kuramoto mean field game

R Carmona, Q Cormier, HM Soner - Communications in Partial …, 2023 - Taylor & Francis
The classical Kuramoto model is studied in the setting of an infinite horizon mean field
game. The system is shown to exhibit both synchronization and phase transition …

Mean field games systems under displacement monotonicity

AR Mészáros, C Mou - SIAM Journal on Mathematical Analysis, 2024 - SIAM
In this note we prove the uniqueness of solutions to a class of mean field games systems
subject to possibly degenerate individual noise. Our results hold true for arbitrary long time …

Long-time behavior of deterministic mean field games with nonmonotone interactions

M Bardi, H Kouhkouh - SIAM Journal on Mathematical Analysis, 2024 - SIAM
We consider deterministic mean field games (MFGs) in all Euclidean space with a cost
functional continuous with respect to the distribution of the agents and attaining its minima in …

C Bernardini, A Cesaroni - Journal of Differential Equations, 2023 - Elsevier
We consider second-order ergodic Mean-Field Games systems in the whole space RN with
coercive potential and aggregating nonlocal coupling, defined in terms of a Riesz interaction …

Coupling by reflection for controlled diffusion processes: Turnpike property and large time behavior of Hamilton–Jacobi–Bellman equations

G Conforti - The Annals of Applied Probability, 2023 - projecteuclid.org
We investigate the long time behavior of weakly dissipative semilinear Hamilton–Jacobi–
Bellman (HJB) equations and the turnpike property for the corresponding stochastic control …

A priori estimates and large population limits for some nonsymmetric Nash systems with semimonotonicity

M Cirant, DF Redaelli - arXiv preprint arXiv:2406.10822, 2024 - arxiv.org
We address the problem of regularity of solutions $ u^ i (t, x^ 1,\ldots, x^ N) $ to a family of
semilinear parabolic systems of $ N $ equations, which describe closed-loop equilibria of …
