On a 2-Relative Entropy [PDF]

open access: yesEntropy, 2021
We construct a 2-categorical extension of the relative entropy functor of Baez and Fritz, and show that our construction is functorial with respect to vertical morphisms.

Compactness and lower semicontinuity in $GSBD$ [PDF]

open access: yesJournal of the European Mathematical Society, 2020
In this paper we prove a compactness and semicontinuity result in GSBD for sequences with bounded Griffith energy. This generalises classical results in ( G )

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.

A categorical characterization of relative entropy on standard Borel spaces [PDF]

open access: yesLogical Methods in Computer Science, 2023
We give a categorical treatment, in the spirit of Baez and Fritz, of relative entropy for probability distributions defined on standard Borel spaces. We define a category suitable for reasoning about statistical inference on standard Borel spaces.

Some Variational Results Using Generalizations of Sequential Lower Semicontinuity

open access: yesFixed Point Theory and Applications, 2010
Kirk and Saliga and then Chen et al. introduced lower semicontinuity from above, a generalization of sequential lower semicontinuity, and they showed that well-known results, such as Ekeland's variational principle and Caristi's fixed point theorem ...

Some remarks on Lower semicontinuity [PDF]

open access: yesIndiana University Mathematics Journal, 2000
The paper is aimed to the extension of some classical lower semicontinuity results of J. Serrin concerning lower semicontinuity of integral functionals \[ u\mapsto \int_\Omega L\bigl(x,u(x),\nabla u(x)\bigr) dx \] for real-valued functions \(u\). Serrin considered two kinds of convergence, according to the growth condition of the Lagrangian: \(L^1 ...

The stability of minimal solution sets for set optimization problems via improvement sets

open access: yesJournal of Inequalities and Applications, 2023
In this paper we investigate the stability of solution sets for set optimization problems via improvement sets. Some sufficient conditions for the upper semicontinuity, lower semicontinuity, and compactness of E-minimal solution mappings are given for ...

Lower semicontinuity for the Helfrich problem [PDF]

open access: yesAnnals of Global Analysis and Geometry, 2020
AbstractWe minimise the Canham–Helfrich energy in the class of closed immersions with prescribed genus, surface area, and enclosed volume. Compactness is achieved in the class of oriented varifolds. The main result is a lower-semicontinuity estimate for the minimising sequence, which is in general false under varifold convergence by a counter example ...

Liftings, Young Measures, and Lower Semicontinuity [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2018
This work introduces liftings and their associated Young measures as new tools to study the asymptotic behaviour of sequences of pairs $(u_j,Du_j)j$ for $(u_j)_j \in \mathrm{BV}(Ω;\mathbb{R}^m)$ under weak* convergence. These tools are then used to prove an integral representation theorem for the relaxation of the functional \[ \mathcal{F}\colon u\to ...

Semicontinuity and closedness of parametric generalized lexicographic quasiequilibrium problems

open access: yesJournal of Inequalities and Applications, 2016
This paper is mainly concerned with the upper semicontinuity, closedness, and the lower semicontinuity of the set-valued solution mapping for a parametric lexicographic equilibrium problem where both two constraint maps and the objective bifunction ...
