Equi-integrability results for 3D-2D dimension reduction problems
ESAIM: Control, Optimisation and Calculus of Variations, Tome 7 (2002), pp. 443-470.

3D-2D asymptotic analysis for thin structures rests on the mastery of scaled gradients α u ε |1 ε 3 u ε bounded in L p (Ω; 9 ),1<p<+. Here it is shown that, up to a subsequence, u ε may be decomposed as w ε +z ε , where z ε carries all the concentration effects, i.e. α w ε |1 ε 3 w ε p is equi-integrable, and w ε captures the oscillatory behavior, i.e. z ε 0 in measure. In addition, if {u ε } is a recovering sequence then z ε =z ε (x α ) nearby Ω.
