Abstract:
We consider the eigenvalue problem for a two-dimensional Laplace operator with mixed boundary conditions (Zaremba problem), which (presumably) has a smooth solution inside the domain. Calculations show that the operator $-\Delta$ has a negative eigenvalue, i.e., it is not positive definite.
Keywords:
numerical algorithms without saturation, Zaremba problem, eigenvalue problem with mixed boundary conditions.
