Research Abstract |
We studied the initial-boundary problem for spherical symmetric solutions introduced by F.John, where boundary is a sphere. We formulated concretely nonlinear boundary condition so called traction problem for spherical symmetric solution. As the first step toward to nonlinear problem, we established that the energy inequalities for linear initial-boundary problem hold in the interior and exterior domain for any material.
