Orthogonal eigenvectors and singular vectors of tensors

Alvaro Ribot, Anna Seigal, Piotr Zwiernik

The spectral theorem says that a real symmetric matrix has an orthogonal basis of eigenvectors and that, for a matrix with distinct eigenvalues, the basis is unique (up to signs).…

Gram Determinants of Real Binary Tensors

Anna Seigal

A binary tensor consists of $2^{n}$ entries arranged into hypercube format $2 \times 2 \times \dots \times 2$ . There are $n$ ways to flatten such a tensor into a matrix of size $2 \…

Singular Vectors of Orthogonally Decomposable Tensors

Elina Robeva, Anna Seigal

Orthogonal decomposition of tensors is a generalization of the singular value decomposition of matrices. In this paper, we study the spectral theory of orthogonally decomposable te…
