Up to now, the eigenvalues of a tree T with a perfect matching have been studied by several authors (see [2,7,8]). However, when a tree has no perfect matching but has an m-matching M, namely, M consists of … WitrynaWe develop a tool for locating eigenvalues of the normalized Laplacian matrix of trees. This is obtained by extending an algorithm designed for the adjacency matrix, due to Jacobs and Trevisan (2011). As an application, we study the multiplicity of normalized Laplacian eigenvalues of small diameter trees. Our main result is the …

Therefore, the analogous question can be posed about locating multiple eigenvalues of a Hermitian A(x;y;z). We will formulate an extension of our results to complex Hermitian matrices but will concentrate on the real symmetric case in our proofs. The problem of locating the points of eigenvalue multiplicity is of practical ...

The sum of the eigenvalues is equal to the number of variables entered into the PCA; however, the eigenvalues will range from greater than one to near zero. An eigenvalue of 1 means that the principal component would explain about one variable’s worth of the variability.
