The nonlinear membrane model : a Young measure and varifold formulation

Med Lamine Leghmizi, Christian Licht, Gérard Michaille (2005)

ESAIM: Control, Optimisation and Calculus of Variations

We establish two new formulations of the membrane problem by working in the space of W Γ 0 1 , p ( Ω , 𝐑 3 ) -Young measures and W Γ 0 1 , p ( Ω , 𝐑 3 ) -varifolds. The energy functional related to these formulations is obtained as a limit of the 3 d formulation of the behavior of a thin layer for a suitable variational convergence associated with the narrow convergence of Young measures and with some weak convergence of varifolds. The interest of the first formulation is to encode the oscillation informations on the gradients minimizing sequences...

Weak uniqueness and partial regularity for the composite membrane problem

Sagun Chanillo, Carlos E. Kenig (2008)

Journal of the European Mathematical Society

We study the composite membrane problem in all dimensions. We prove that the minimizing solutions exhibit a weak uniqueness property which under certain conditions can be turned into a full uniqueness result. Next we study the partial regularity of the solutions to the Euler–Lagrange equation associated to the composite problem and also the regularity of the free boundary for solutions to the Euler–Lagrange equations.
