Weak uniqueness and partial regularity for the composite membrane problem
نویسنده
چکیده
Abstract. 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.

Existence and uniqueness of weak solutions for a class of nonlinear divergence type diffusion equations
In this paper, we study the Neumann boundary value problem of a class of nonlinear divergence type diffusion equations. By a priori estimates, difference and variation techniques, we establish the existence and uniqueness of weak solutions of this problem.
متن کاملArens Regularity and Weak Amenability of Certain Matrix Algebras
Motivated by an Arens regularity problem, we introduce the concepts of matrix Banach space and matrix Banach algebra. The notion of matrix normed space in the sense of Ruan is a special case of our matrix normed system. A matrix Banach algebra is a matrix Banach space with a completely contractive multiplication. We study the structure of matrix Banach spaces and matrix Banach algebras. Then we...
متن کاملWeak Time Regularity and Uniqueness for a Q-Tensor Model
The coupled Navier-Stokes and Q-Tensor system is one of the models used to describe the behavior of the nematic liquid crystals. The existence of weak solutions and a uniqueness criteria have been already studied (see [11] for a Cauchy problem in the whole R3 and [7] for a initial-boundary problem in a bounded domain Ω). Nevertheless, results on strong regularity have only been treated in [11] ...
متن کامل$(F,varphi ,alpha )_{s}$-contractions in $b$-metric spaces and applications
In this paper, we introduce more general contractions called $varphi $-fixed point point for $(F,varphi ,alpha )_{s}$ and $(F,varphi ,alpha )_{s}$-weak contractions. We prove the existence and uniqueness of $varphi $-fixed point point for $(F,varphi ,alpha )_{s}$ and $(F,varphi ,alpha)_{s}$-weak contractions in complete $b$-metric spaces. Some examples are supplied to sup...
متن کاملTransonic Shocks in Multidimensional Divergent Nozzles
We establish existence, uniqueness and stability of transonic shocks for steady compressible non-isentropic potential flow system in a multidimensional divergent nozzle with an arbitrary smooth cross-section, for a prescribed exit pressure. The proof is based on solving a free boundary problem for a system of partial differential equations consisting of an elliptic equation and a transport equa...
