ABSTRACT
Let O be an open bounded domain in $$\mathbb{R}^N (N\geq3)$$ with smooth boundary $$\partial\Omega, 0\in\partial\Omega$$ . We are concerned with the critical Neumann problem where $$0 < \mu < \bar{\mu}=(\frac{N-2}{2})^2,\,\,2^*=\frac{2N}{N-2},\,\,\,\,\lambda > 0$$ and Q( x) is a positive continuous function on $$\overline{\Omega}$$ . Using Moser iteration, we give an asymptotic characterization of solutions for (*) at the origin. Under some conditions on Q, ï¿½, we, by means of a variational method, prove that there exists $$\lambda_0=\lambda_0(\mu) > 0$$ such that for every $$\lambda > \lambda_0$$ , problem (*) has a positive solution and a pair of sign-changing solutions.

The unsteady laminar boundary-layer flow over a continuously stretching surface in a viscous and incompressible quiescent fluid is studied. The unsteadiness in the flow and temperature fields is caused by the time dependence of the stretching velocity and the surface heat flux. The nonlinear...

It is well known that the classical local projection method as well as residual-based stabilization techniques, as for instance streamline upwind Petrov-Galerkin (SUPG), are optimal on isotropic meshes. Here we extend the local projection stabilization for the Navier-Stokes system to anisotropic...
