a. Find the eigenvalues \lambda_+ and\lambda_+ larger and smaller or equal or conjugate, respectively, of the coefficient matrix A, Consider the given matrix. ( -1 1 -5 1). Find the eigenvectors of the matrix. (Enter your ans...
We then introduce a new class of estimators to determine the number of those relevant factors. Unlike existing estimators, our estimators use not only the eigenvalues of the covariance matrix, but also its eigenvectors. We find that incorporating partial sums of the eigenvectors into our estimators...
A cycle of size l is denoted by Cl. The nullity (or rank) of a molecular graph G has a number of important applications in physical chemistry. In quantum mechanics, Hückel theory (for the molecule corresponding to molecular graph G) says that the eigenvectors of the adjacency matrix A(G...

Although the topology of a non-interacting linear system can be characterized by the Chern number that is computed from its eigenvectors, the topology of a nonlinear system is classified by the nonlinear Chern number, which utilizes the nonlinear extension of the eigenequation. In weakly nonlinear ...
Network science investigates methodologies that summarise relational data to obtain better interpretability. Identifying modular structures is a fundamental task, and assessment of the coarse-grain level is its crucial step. Here, we propose principled,
One may wonder if these two different random procedures should give similar distributions in this or other numerical problems. The answer isno. For example, say that our problem is to compute the kernel of a given matrixand we want to study the expected value of the associated condition numbe...

Multi-dimensional scaling showed that the first and second eigenvectors explained 21% and 9% of the distance variables, respectively (Figure 4). When referenced to the Affymetrix reference, the 90 individuals were dispersed in a plot of eigenvetors, suggesting that the Korean population can be ...
