Relaxation of functionals with linear growth: interactions of emerging measures and free discontinuities
Stefan Krömer, Martin Kružík, Elvira Zappale
For an integral functional defined on functions featuring a prototypical strong interaction term between and , we calculate its relaxation in th…
Global invertibility for orientation-preserving Sobolev maps via invertibility on or near the boundary
Stefan Krömer
By a result of John Ball (1981), a locally orientation preserving Sobolev map is almost everywhere globally invertible whenever its boundary values admit a homeomorphic extension.…
Quasistatic viscoelasticity with self-contact at large strains
Stefan Krömer, Tomáš Roubiček
The frame-indifferent viscoelasticity in Kelvin-Voigt rheology at large strains is formulated in the reference configuration (i.e. using the Lagrangian approach) considering also t…
Heterogeneous thin films: Combining homogenization and dimension reduction with directors
Carolin Kreisbeck, Stefan Krömer
We analyze the asymptotic behavior of a multiscale problem given by a sequence of integral functionals subject to differential constraints conveyed by a constant-rank operator with…
Sequential weak continuity of null Lagrangians at the boundary
Agnieszka Kalamajska, Stefan Kroemer, Martin Kruzik
We show weak* in measures on / weak- sequential continuity of , where is a null Lagrangian for , i…
On properness and related properties of quasilinear systems on unbounded domains
Stefan Krömer, Markus Lilli
The purpose of this paper is to provide tools for analyzing the compactness of sequences in Sobolev spaces, in particular if the sequence gets mapped onto a compact set by some non…
