A Pointwise Characterisation of the PDE System of Vectorial Calculus of Variations in $L^{\infty}$

Birzhan Ayanbayev, Nikos Katzourakis

Let $n, N \in N$ with $Ω \subseteq R^{n}$ open. Given $H \in C^{2} (Ω \times R^{N} \times R^{N n}),$ we consider the functional \[ \tag{1} \label{1} E_\infty…

Second Order $L^{\infty}$ Variational Problems and the $\infty$ -Polylaplacian

Nikos Katzourakis, Tristan Pryer

In this paper we initiate the study of $2$ nd order variational problems in $L^{\infty}$ , seeking to minimise the $L^{\infty}$ norm of a function of the hessian. We also derive and stud…

$D$ -solutions to the system of vectorial Calculus of Variations in $L^{\infty}$ via the singular value problem

Gisella Croce, Nikos Katzourakis, Giovanni Pisante

For $H \in C^{2} (R^{N \times n})$ and $u : Ω \subseteq R^{n} \to R^{N}$ , consider the system \[ \label{1}\mathrm{A}\_\infty u\, :=\,\Big(\mathrm{H}\_P…

Existence of 1D vectorial Absolute Minimisers in $L^{\infty}$ under minimal assumptions

Hussien Abugirda, Nikos Katzourakis

We prove the existence of vectorial Absolute Minimisers in the sense of Aronsson to the supremal functional $E_{\infty} (u, Ω^{'}) = ∥ L (\cdot, u, D u) ∥_{L^{\infty} (Ω^{'})}$ , $Ω'\Subs…
