چکیده
Let $\Omega \subset \mathbb{R}^3$ be an open and bounded set with Lipschitz boundary outward unit normal $\nu$. For $11 \quad \text{if $p \frac32$.}$$ Specifically, there exists a constant $c=c(p,\Omega,r)>0$ such that \[ \|P \|_{L^p}\leq c\,\left(\|\operatorname{sym} \|_{L^p} \|\operatorname{dev}\operatorname{sym} \|_{L^{r}}\right) \] holds all $P\in W^{1,\,p, \, r}_0(\operatorname{dev}\operatorname{sym}\operatorname{Curl})$. Here, $\operatorname{dev} X := -\frac13 \operatorname{tr}(X)\,\mathbb{1}$ denotes deviatoric (trace-free) part $3 3$ matrix $X$ condition is understood suitable weak sense.

Conserved Currents and the Energy Momentum Tensor in Conformally Invariant Theories for General Dimensions
The implications of conformal invariance, as relevant in quantum field theories at a renormalisation group fixed point, are analysed with particular reference to results for correlation functions involving conserved currents and the energy momentum tensor. Ward identities resulting from conformal invariance are discussed. Explicit expressions for two and three point functions, which are essenti...
متن کاملConformally invariant differential operators on tensor densities
Let Fλ be the space of tensor densities on R n of degree λ (or, equivalently, of conformal densities of degree −λn) considered as a module over the Lie algebra o(p+1, q+1). We classify o(p+1, q+1)-invariant bilinear differential operators from Fλ ⊗ Fμ to Fν . The classification of linear o(p + 1, q + 1)invariant differential operators from Fλ to Fμ already known in the literature (see [6, 9]) i...
متن کاملConformally invariant bending energy for hypersurfaces
The most general conformally invariant bending energy of a closed four-dimensional surface, polynomial in the extrinsic curvature and its derivatives, is constructed. This invariance manifests itself as a set of constraints on the corresponding stress tensor. If the topology is fixed, there are three independent polynomial invariants: two of these are the straighforward quartic analogues of the...
متن کاملConformally Covariant Differential Operators: Symmetric Tensor Fields
We extend previous work on conformally covariant differential operators to consider the case of second order operators acting on symmetric traceless tensor fields. The corresponding flat space Green function is explicitly constructed and shown to be in accord with the requirements of conformal invariance. PACS: 03.70.+k; 11.10.Kk; 11.25.Hf; 11.30.Ly
متن کاملKorn Inequalities In Orlicz Spaces
We use gradient estimates for solutions of elliptic equations to obtain Korn’s inequality for fields with zero trace from Orlicz–Sobolev classes. As outlined for example in the monographs of Málek, Nečas, Rokyta, Růžička [MNRR], of Duvaut and Lions [DL] and of Zeidler [Ze], the well-posedness of many variational problems arising in fluid mechanics or in the mechanics of solids heavily depends o...
