A sufficient and necessary condition for $A$ -quasiaffinity

Stefan Schiffer

We consider a homogeneous, constant rank differential operator $A$ and prove a characterisation theorem for $A$ -quasiaffine functions in the spirit of Ball, Cur…

On symmetric div-quasiconvex hulls and divsym-free $L^{\infty}$ -truncations

Linus Behn, Franz Gmeineder, Stefan Schiffer

We establish that for any non-empty, compact set $K \subset R_{sym}^{3 \times 3}$ the $1$ - and $\infty$ -symmetric div-quasiconvex hulls $K^{(1)}$ and $K^{(\infty)}$ …

$L^{\infty}$ -truncation of closed differential forms

Stefan Schiffer

In this paper, we prove that for each closed differential form $u \in L^{1} (R^{N}, (R^{N})^{*} \land ... \land (R^{N})^{*})$ , which is almost in $L^{\inft…
