A frame-indifferent rank-one convex function in three dimensions which is not quasiconvex
Sergio Conti, Georg Dolzmann, Patrick Dondl
We construct a function which is frame-indifferent, for all , rank-one convex, but not quasiconvex. In a nei…
Uniform approximation of almost isometric maps
Sergio Conti, Georg Dolzmann, Stefan Müller
This paper shows that an almost-isometric Sobolev map from a Lipschitz subset of an oriented manifold into another oriented manifold can be approximated by a map of class $…
Local Well-Posedness of a Model for Stress-Driven Growth in the Presence of Nutrients
Helmut Abels, Julian Blawid, Georg Dolzmann
A model for morphoelastic growth, that is, growth influenced by elastic stress, driven by the absorption of nutrients is considered. The model features a multiplicative decompositi…
Regularity Properties of Solutions of a Model for Morphoelastic Growth in the Presence of Nutrients in One Spatial Dimension
Julian Blawid, Georg Dolzmann
Regularity properties of solutions for a class of quasi-stationary models in one spatial dimension for stress-modulated growth in the presence of a nutrient field are proven. At a…
Optimal rigidity estimates for maps of a compact Riemannian manifold to itself
Sergio Conti, Georg Dolzmann, Stefan Müller
Let be a smooth, compact, connected, oriented Riemannian manifold, and let be an isometric embedding. We show that a Sobolev map which…
Analytical and numerical relaxation results for models in soil mechanics
Florian Behr, Georg Dolzmann, Klaus Hackl +1
A variational model of pressure-dependent plasticity employing a time-incremental setting is introduced. A novel formulation of the dissipation potential allows one to construct th…
Stress-modulated growth in the presence of nutrients -- existence and uniqueness in one spatial dimension
Kira Bangert, Georg Dolzmann
Existence and uniqueness of solutions for a class of models for stress-modulated growth is proven in one spatial dimension. The model features the multiplicative decomposition of t…
Variational models for the interaction of surfactants with curvature -- existence and regularity of minimizers in the case of flexible curves
Christopher Brand, Georg Dolzmann, Alessandra Pluda
Existence and regularity of minimizers for a geometric variational problem is shown. The variational integral models an energy contribution of the interface between two immiscible…
On the theory of relaxation in nonlinear elasticity with constraints on the determinant
Sergio Conti, Georg Dolzmann
We consider vectorial variational problems in nonlinear elasticity of the form , where is continuous on matrices with positive determinant and diverges to in…
Relaxation of a model energy for the cubic to tetragonal phase transformation in two dimensions
Sergio Conti, Georg Dolzmann
We consider a two-dimensional problem in nonlinear elasticity which corresponds to the cubic-to-tetragonal phase transformation. Our model is frame invariant and the energy density…
Strong solutions for the Beris-Edwards model for nematic liquid crystals with homogeneous Dirichlet boundary conditions
Helmut Abels, Georg Dolzmann, YuNing Liu
Existence and uniqueness of local strong solution for the Beris--Edwards model for nematic liquid crystals, which couples the Navier-Stokes equations with an evolution equation for…
Well-posedness of a fully-coupled Navier-Stokes/Q-tensor system with inhomogeneous boundary data
Helmut Abels, Georg Dolzmann, YuNing Liu
We prove short-time well-posedness and existence of global weak solutions of the Beris--Edwards model for nematic liquid crystals in the case of a bounded domain with inhomogeneous…
Korn's second inequality and geometric rigidity with mixed growth conditions
Sergio Conti, Georg Dolzmann, Stefan Müller
Geometric rigidity states that a gradient field which is -close to the set of proper rotations is necessarily -close to a fixed rotation, and is one key estimate in nonli…
The div-curl lemma for sequences whose divergence and curl are compact in W^{-1,1}
Sergio Conti, Georg Dolzmann, Stefan Müller
It is shown that converges weakly to if $u_k\weakto u$ weakly in and $v_k\weakly v$ weakly in with , , under t…
