We consider the Schrödinger operator $-h^{2}\partial _{x}^{2}+V(x)$ on a half-line, where V is a compactly supported potential which is positive near the end-point of its support. We prove that the ...
In this paper several algorithms for finding the eigenvalues of real symmetric matrices are discussed and compared. The algorithms have been programmed by the author for the IBM 7094. Descriptions of ...
