## Dirichlet and Neumann eigenvalue problems on domains in Euclidean spaces.(English)Zbl 0892.35115

The author obtains some inequalities for the eigenvalues of Dirichlet and Neumann boundary problems for general classes of operators (or systems of operators) acting in $$L^2(\Omega)$$ (or $$L^2(\Omega, \mathbb{C}^m))$$, $$\Omega \subset\mathbb{R}^d$$, $$d\geq 1$$.
