Well-posedness and convexity in vector optimization

open access: yes, 2003
We study a notion of well-posedness in vector optimization through the behaviour of minimizing sequences of sets, defined in terms of Hausdorff set-convergence.

Self‐calibrated B1+ and B0 Field Inhomogeneities Estimation (SAFE) in 3D Magnetic Resonance Fingerprinting

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 6, Page 2803-2811, December 2026.
ABSTRACT Purpose To develop SAFE, a self‐calibrated framework to estimate B1+ and B0 field inhomogeneities directly from conventional magnetic resonance fingerprinting (MRF) acquisitions and improve its quantification accuracy. Methods SAFE utilized a two‐step approach. First, two physics‐informed image markers are extracted from the MRF data to create

Stochastic Galerkin and Monte Carlo Methods for Parabolic Problems: Numerical Performance of Variational Matrix‐Free Approximations

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Stochastic Galerkin methods offer unexplored potential for the numerical simulation of parabolic problems with random variables, in particular if they are combined with variational discretizations of the space and time variables. Due to the high dimensionality, the solution of the arising algebraic systems do not become feasible without ...

On the well-posedness of large-scale interconnected systems

open access: yes, 1980
In this paper, we give a precise definition of well-posedness for a large-scale interconnected system, and derive several criteria for well-posedness.

Performance of a Mixed Least‐Squares Finite Element Formulation With Application in Poroelasticity

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT A mixed least‐squares finite element method (LSFEM), previously proposed for the theory of porous media (TPM), is further investigated in this work. Finite deformation of a fully saturated, incompressible solid–fluid binary system is studied using the LSFEM.

Potential games and well posedness properties

open access: yes, 2008
The aim of this paper is to study Potential Games which are a special class of games; in fact their properties are dictated by a single function called the potential function.

A Numerical Study of a Weakly Symmetric Dual‐Mixed Finite Element Method for the Stokes Source Problem With Velocity Postprocessing

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT We present a numerical study of a weakly symmetric dual‐mixed finite element method for the Stokes source problem, in which the Cauchy stress is the primary unknown and its symmetry is imposed weakly through a vorticity Lagrange multiplier. Viewing the scheme as the incompressible limit of the reduced‐symmetry mixed elasticity framework, we ...

Well-posedness of minimal dRGT massive gravity

open access: yesJournal of High Energy Physics
Ghost-free dRGT massive gravity is a subtle theory, even at the classical level. Its viability depends on Vainshtein screening, which is an intrinsically non-linear phenomenon, and thus understanding the full non-linear dynamics of the theory is crucial.

Well-Posedness for a Class of Strongly Mixed Variational-Hemivariational Inequalities with Perturbations

open access: yesJournal of Applied Mathematics, 2012
The concept of well-posedness for a minimization problem is extended to develop the concept of well-posedness for a class of strongly mixed variational-hemivariational inequalities with perturbations which includes as a special case the class of ...
