Representation Theorems and Variational Principles for Self-Adjoint Operator Matrices
A. A. Vladimirov Federal Research Center "Computer Science and Control" of Russian Academy of Sciences
Abstract:
We use the notion of triples $\mathfrak{D}^+\hookrightarrow \mathfrak{H}\hookrightarrow\mathfrak{D}^-$ of Hilbert spaces to develop an analog of the Friedrichs extension procedure for a class of nonsemibounded operator matrices. In addition, we suggest a general approach (stated in the same terms) to the construction of variational principles for the eigenvalues of such matrices.
Keywords:
rigged space, operator matrix, self-adjoint extension, variational principle.
