L^p -trace-free version of the generalized Korn inequality for incompatible tensor fields in arbitrary dimensions
Résumé
For n ≥ 3 and 1 < p < ∞ we prove an L^p-version of the generalized trace-free Korn-type inequality for incompatible, p-integrable tensor fields P : Ω → R^(n×n) having p-integrable generalized Curl_n and generalized vanishing tangential trace, more precisely there exists a constant c = c(n, p, Ω) such that |P|_(L^p) ≤ c (|dev_n sym P|_(L^p) + |Curl_n P|_(L^p), where the generalized Curl_n is given by (Curl_n P)_{ijk} := ∂_iP_{kj} − ∂_jP_{ki} and dev_n X := X − 1_n tr(X) · id denotes the deviatoric (trace-free) part of the square matrix X. The improvement towards the three-dimensional case comes from a novel matrix representation of the generalized cross product.
