چکیده

For $10$ such that \[ \|{ P }\|_{L^p(\Omega,\mathbb{R}^{3\times3})}\leq c\,\left(\|{\operatorname{dev} \operatorname{sym} }\|_{L^p(\Omega,\mathbb{R}^{3\times3})} + \operatorname{dev} \operatorname{Curl} }\|_{L^p(\Omega,\mathbb{R}^{3\times3})}\right) \] holds all $P\in \Omega,\mathbb{R}^{3\times3})$, i.e., W^{1,\,p}(\operatorname{Curl}; \Omega,\mathbb{R}^{3\times3})$ with vanishing tangential trace P\times \nu=0 on \partial\Omega$ where $\nu$ denotes outward unit normal vector field to $\partial\Omega$ and $\operatorname{dev} := -\frac13 \operatorname{tr}(P)\,\mathbb{1}_3$ deviatoric (trace-free) part $P$. We also show norm equivalence }\|_{L^p(\Omega,\mathbb{R}^{3\times3})}+\|{\operatorname{Curl} \operatorname{dev}\operatorname{Curl} These estimates hold true only relatively open (non-empty) subset $\Gamma \subseteq boundary.

Korn 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...

Exact Scaling Exponents in Korn and Korn-Type Inequalities for Cylindrical Shells

Understanding asymptotics of gradient components in relation to the symmetrized gradient is important for the analysis of buckling of slender structures. For circular cylindrical shells we obtain the exact scaling exponent of the Korn constant as a function of shell’s thickness. Equally sharp results are obtained for individual components of the gradient in cylindrical coordinates. We also deri...

Strategies for Visualizing Tensor Fields in more than two Dimensions

Tensor field visualization aims at the depiction of the full information contained in the underlying data set or the extraction and display of specific features. Here, we focus on the first task and evaluate various methods with regard to their power of providing an intuitive visual representation. Tensor fields are reviewed in a differential geometric context and we provide a coordinate-free d...

Sharp conditions for Korn inequalities in Orlicz spaces

We show that Korn’s inequality in Orlicz spaces holds if and only if the Orlicz function satisfies the ∆2and the ∇2-condition. This result applies to several types of Korn’s inequality. In particular we show that Korn’s inequality is false in L, in L logL, in Exp and in L∞. MSC (2000): 74 B, 74 G, 76 D, 49 J.

Perturbation Theory for Antisymmetric Tensor Fields in Four Dimensions

Perturbation theory for a class of topological field theories containing antisymmetric tensor fields is considered. These models are characterized by a supersymmetric structure which allows to establish their perturbative finiteness.
