Maximal Classes For Lower And Upper Semicontinuous Strong Świątkowski Functions

open access: yesDemonstratio Mathematica, 2014
In this paper, we characterize the maximal additive and multiplicative classes for lower and upper semicontinuous strong Świątkowsk functions and lower and upper semicontinuous extra strong Świątkowski functions.

Some characterizations of error bound for non-lower semicontinuous functions

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we study the error bound of non-lower semicontinuous functions. First, we extend the concepts of strong slope and global slope to the non-lower semicontinuous functions.

Some fixed-point theorems for a general class of mappings in modular G-metric spaces [PDF]

open access: yesArab Journal of Mathematical Sciences, 2022
Purpose – This paper aims to prove some fixed-point theorems for a general class of mappings in modular G-metric spaces. The results of this paper generalize and extend several known results to modular G-metric spaces, including the results of Mutlu et ...

On the Lower Semicontinuity of Supremal Functionals [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2003
Summary: In this paper we study the lower semicontinuity problem for a supremal functional of the form \[ F(u,\Omega )= \underset {x\in \Omega } {\text{ess\,sup}} f(x,u(x),Du(x)) \] with respect to the strong convergence in \(L^\infty (\Omega )\), furnishing a comparison with the analogous theory developed by Serrin for integrals.

Characterization of lower semicontinuous convex functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1992
We prove that a lower semicontinuous function defined on a reflexive Banach space is convex if and only if its Clarke subdifferential is monotone.

Proximal gradient methods beyond monotony [PDF]

open access: yesJournal of Nonsmooth Analysis and Optimization, 2023
We address composite optimization problems, which consist in minimizing the sum of a smooth and a merely lower semicontinuous function, without any convexity assumptions. Numerical solutions of these problems can be obtained by proximal gradient methods,

Weak Lower Semicontinuity of Integral Functionals and Applications [PDF]

open access: yesSIAM Review, 2017
Minimization is a reoccurring theme in many mathematical disciplines ranging from pure to applied ones. Of particular importance is the minimization of integral functionals that is studied within the calculus of variations. Proofs of the existence of minimizers usually rely on a fine property of the involved functional called weak lower semicontinuity.

Asymptotic Behavior of Resolvents of a Convergent Sequence of Convex Functions on Complete Geodesic Spaces

open access: yesAxioms, 2022
The asymptotic behavior of resolvents of a proper convex lower semicontinuous function is studied in the various settings of spaces. In this paper, we consider the asymptotic behavior of the resolvents of a sequence of functions defined in a complete ...

Lower semicontinuity for functionals defined on piecewise rigid functions and on GSBD [PDF]

open access: yesJournal of Functional Analysis, 2021
In this work, we provide a characterization result for lower semicontinuity of surface energies defined on piecewise rigid functions, i.e., functions which are piecewise affine on a Caccioppoli partition where the derivative in each component is a skew symmetric matrix.
