A Quasi-Variational Inequality Problem Arising in the Modeling of Growing Sandpiles [PDF]

open access: yes, 2012
Existence of a solution to the quasi-variational inequality problem arising in a model for sand surface evolution has been an open problem for a long time.

Quasivariational solutions for first order quasilinear equations with gradient constraint [PDF]

open access: yes, 2012
We prove the existence of solutions for an evolution quasi-variational inequality with a first order quasilinear operator and a variable convex set, which is characterized by a constraint on the absolute value of the gradient that depends on the solution

A class of stationary nonlinear Maxwell systems [PDF]

open access: yes, 2009
We study a new class of electromagnetostatic problems in the variational framework of the subspace of $W^{1,p}(\Omega)^3$ of vector functions with zero divergence and zero normal trace, for $p>6/5$, in smooth, bounded and simply connected domains ...

An exact viscosity solution to a Hamilton–Jacobi–Bellman quasi-variational inequality for animal population management

open access: yesJournal of Mathematics in Industry, 2019
We formulate a stochastic impulse control model for animal population management and a candidate of exact solutions to a Hamilton–Jacobi–Bellman quasi-variational inequality.

A theoretical view of existence results by using fixed point theory for quasi-variational inequalities

open access: yesApplied Mathematics in Science and Engineering, 2023
In this paper, we present new existence results for the quasi-variational inequality problem (QV I) in reflexive Banach spaces using the fixed point method with quasi-monotonicity and local upper sign-continuity assumptions.

Metastable states, quasi-stationary distributions and soft measures [PDF]

open access: yes, 2015
We establish metastability in the sense of Lebowitz and Penrose under practical and simple hypothesis for (families of) Markov chains on finite configuration space in some asymptotic regime, including the case of configuration space size going to ...

On soft capacities, quasi-stationary distributions and the pathwise approach to metastability [PDF]

open access: yes, 2020
Motivated by the study of the metastable stochastic Ising model at subcritical temperature and in the limit of a vanishing magnetic field, we extend the notion of ($\kappa$, $\lambda$)-capacities between sets, as well as the associated notion of soft ...

Generalized Quasi-Variational-Like Inequality Problem [PDF]

open access: yesMathematics of Operations Research, 1993
This paper gives some very general results on the generalized quasi-variational-like inequality problem. Since the problem includes all the existing extensions of the classical variational inequality problem as special cases, our existence theorems extend the previous results in the literature by relaxing both continuity and concavity of the ...

Modified Inertial Forward–Backward Algorithm in Banach Spaces and Its Application

open access: yesMathematics, 2021
In this paper, we present a new modified inertial forward–backward algorithm for finding a common solution of the quasi-variational inclusion problem and the variational inequality problem in a q-uniformly smooth Banach space.

Certain remarks on a class of evolution quasi-variational inequalities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We prove two existence theorems, one for evolution quasi-variational inequalities and the other for a time-dependent quasi-variational inequality modeling the quasi-static problem of elastoplasticity with combined kinetic-isotropic hardening.
