Abstract

For n2n\ge2 and 1<p<1<p<\infty we prove an LpL^p-version of the generalized Korn-type inequality for incompatible, pp-integrable tensor fields P:ΩRn×nP:\Omega \to \mathbb{R}^{n\times n} having pp-integrable generalized Curl\underline{\operatorname{Curl}} and generalized vanishing tangential trace Pτl=0P\,\tau_l=0 on Ω\partial \Omega, denoting by {τl}l=1,,n1\{\tau_l\}_{l=1,\ldots, n-1} a moving tangent frame on Ω\partial\Omega, more precisely we have: PLp(Ω,Rn×n)c(symPLp(Ω,Rn×n)+CurlPLp(Ω,(so(n))n)),\| P \|_{L^p(\Omega,\mathbb{R}^{n\times n})}\leq c\,(\| \operatorname{sym} P\|_{L^p(\Omega,\mathbb{R}^{n \times n})} + \|\underline{\operatorname{Curl}} P \|_{L^p(\Omega,(\mathfrak{so}(n))^n)} ), where the generalized Curl\underline{\operatorname{Curl}} is given by (Curl)ijk:=iPkjjPki (\underline{\operatorname{Curl}})_{ijk} :=\partial_i P_{kj}-\partial_j P_{ki} and c=c(n,p,Ω)>0c=c(n,p,\Omega)>0.
