) can now be decomposed using the set of eigenfunctions and eigenvalues of the Hamiltonian. For instance, if countable within a compact symmetry group, they are \(\phi _n\) and \(E_n\) so that \(G\left( x, t; x', t'\right) = \sum _{n} \phi _n^*(x')\phi _n(x) e^...
one from a more geometric perspective and one proceeding via Cramer’s rule.) It was certainly something of a surprise to me that there is no explicit appearance of the components of in the formula (1) (though they do indirectly appear through their effect on the eigenvalues ; for instance...
What do eigenvectors and eigenvalues tell you about the transformation geometrically? How do we get a multiplicity of eigenvalues? Find the eigenvalues and eigenfunctions to y'' + \lambda y = 0, where y'(0) = 0, y( \pi) = 0, y = y(x) ...
if an n \xd7 n matrix a is both symmetric and orthogonal, what can you say about the eigenvalues of a? what about the eigenspaces? Find the eigenvalues and singular values for A=\begin{bmatrix} 0 & 2 \\ -4 & 6 \end{bmatrix}. Which of the following are eigenfunctions of the op...
What can one say about the eigenvalues of the sum ? There are now many ways to answer this question precisely; one of them, introduced by Allen and myself many years ago, is that there exists a certain triangular array of numbers called a “hive” that has as its boundary values. On ...
electrons–nuclei and nuclei–nuclei potential energy terms. The second term is the kinetic energy operator of the nuclei. Let us consider the eigenfunctions\(\left\{ \chi _j(\textbf{r}; \textbf{R})\right\} _{j=0,\infty }\)and the corresponding eigenvalues\(\left\{ \epsilon _j(\tex...
Since is upper triangular, it has its eigenvalues on the diagonal. Since , there are two distinct eigenvalues and hence, is diagonalizable. Indeed, with we get The matrix exponential of is Hence, the solution of , is How is this related to the solution of ? How far is it away? Of cou...
