Weak solutions to Fokker–Planck equations and mean field games

A Porretta - Archive for Rational Mechanics and Analysis, 2015 - Springer
We deal with systems of PDEs, arising in mean field games theory, where viscous Hamilton–
Jacobi and Fokker–Planck equations are coupled in a forward-backward structure. We …

Parabolic capacity and soft measures for nonlinear equations

J Droniou, A Porretta, A Prignet - Potential Analysis, 2003 - Springer
We first introduce, using a functional approach, the notion of capacity related to the parabolic
p-Laplace operator. Then we prove a decomposition theorem for measures (in space and …

Equivalence between entropy and renormalized solutions for parabolic equations with smooth measure data

J Droniou, A Prignet - Nonlinear Differential Equations and Applications …, 2007 - Springer
We consider the nonlinear heat equation (with Leray-Lions operators) on an open bounded
subset of RN with Dirichlet homogeneous boundary conditions. The initial condition is in L 1 …

Monotone operator theory for unsteady problems in variable exponent spaces

L Diening, P Nägele, M Růžička - Complex variables and elliptic …, 2012 - Taylor & Francis
We introduce function spaces for the treatment of parabolic equations with variable
exponents by means of the theory of monotone operators. We generalize classical results …

Inverse problems for constrained parabolic variational-hemivariational inequalities

S Migórski, D Cai, Y **ao - Inverse Problems, 2023 - iopscience.iop.org
In this paper we study a novel class of inverse problems for parabolic variational–
hemivariational inequalities with a unilateral constraint. A theorem on the well-posedness for …

Convergence of a finite-volume scheme for a heat equation with a multiplicative Lipschitz noise

C Bauzet, F Nabet, K Schmitz… - … and Numerical Analysis, 2023 - esaim-m2an.org
We study here the approximation by a finite-volume scheme of a heat equation forced by a
Lipschitz continuous multiplicative noise in the sense of Itô. More precisely, we consider a …

Convergence analysis of a mixed finite volume scheme for an elliptic-parabolic system modeling miscible fluid flows in porous media

C Chainais-Hillairet, J Droniou - SIAM Journal on Numerical Analysis, 2007 - SIAM
We study a finite volume discretization of a strongly coupled elliptic-parabolic PDE system
describing miscible displacement in a porous medium. We discretize each equation by a …

Convergence of approximations to stochastic scalar conservation laws

S Dotti, J Vovelle - Archive for Rational Mechanics and Analysis, 2018 - Springer
We develop a general framework for the analysis of approximations to stochastic scalar
conservation laws. Our aim is to prove, under minimal consistency properties and bounds …

The turnpike property in semilinear control

D Pighin - ESAIM: Control, Optimisation and Calculus of …, 2021 - esaim-cocv.org
An exponential turnpike property for a semilinear control problem is proved. The state-target
is assumed to be small, whereas the initial datum can be arbitrary. Turnpike results are also …

Goal-oriented error estimation based on equilibrated flux and potential reconstruction for the approximation of elliptic and parabolic problems

E Creusé, S Nicaise, Z Tang - Computers & Mathematics with Applications, 2023 - Elsevier
We present a unified framework for goal-oriented estimates for elliptic and parabolic
problems that combines the dual-weighted residual method with equilibrated flux and …
