Generalizations Of Korn’s Inequality Based On Gradient Estimates In Orlicz Spaces And Applications To Variational Problems In 2D Involving The Trace Free Part Of The Symmetric Gradient
نویسنده
چکیده
We prove variants of Korn’s inequality involving the deviatoric part of the symmetric gradient of fields u : R2 ⊃ Ω → R2 belonging to Orlicz-Sobolev classes. These inequalities are derived with the help of gradient estimates for the Poisson equation in Orlicz spaces. We apply these Korn type inequalities to variational integrals of the form ∫ Ω h ( |εD(u)| ) dx occurring in General Relativity and prove C1,α–regularity results for minimizers under rather general conditions on the N–function h. A further useful tool for this analysis is an appropriate version of the (Sobolev-) Poincaré inequality with εD(u) measuring the distance of u to the holomorphic functions.

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...
متن کاملStrong convergence theorem for a class of multiple-sets split variational inequality problems in Hilbert spaces
In this paper, we introduce a new iterative algorithm for approximating a common solution of certain class of multiple-sets split variational inequality problems. The sequence of the proposed iterative algorithm is proved to converge strongly in Hilbert spaces. As application, we obtain some strong convergence results for some classes of multiple-sets split convex minimization problems.
متن کاملSharp 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.

Korn’s Second Inequality and Geometric Rigidity with Mixed Growth Conditions
Geometric rigidity states that a gradient field which is L-close to the set of proper rotations is necessarily L-close to a fixed rotation, and is one key estimate in nonlinear elasticity. In several applications, as for example in the theory of plasticity, energy densities with mixed growth appear. We show here that geometric rigidity holds also in L + L and in L interpolation spaces. As a fir...
