One example regards the similarity between Symmetric Rayleigh Quotients and Rectangular Rayleigh Quotients. Many ...
Singular values and eigenvalues of tensors a variational approach
Describe the mistake p. 127 states: "The nonzero singular values of A are the square roots of the nonzero eigenvalues of A A^T and are equal to the nonzero eigenvalues of A^T A." But: above it says that the singular values are the square...
Eigenvalues and Singular Values The relationship between the singular values of a given matrix A, and the eigenvalues of the products AAT and ATA is explored. It is also shown that the Euclidean norm of A is the largest singular value.Note...
The asymptotic distribution of singular values and eigenvalues of non-Hermitian block Toeplitz matrices is studied. These matrices are associated with the Fourier series of an univariate function f . The asymptotic distribution of singular values is computed when f belongs to L 2 and is matrix-value...

Problem of defining of relation between eigenvalues and singular values of matrix and matrix-valued functions of the matrix is considered. The problem arises at the interfaces between methods of systems synthesis with use of generalized modal control and quality evaluation of these systems with the he...

We propose a theory of eigenvalues, eigenvectors, singular values, and singular vectors for tensors based on a constrained variational approach much like the Rayleigh quotient for symmetric matrix eigenvalues. These notions are particularly useful in generalizing certain areas where the spectral theory of...
