Hermitian decomposition
Witryna27 sie 2024 · A Hermitian tensor is separable if it has a Hermitian decomposition with only positive coefficients, i.e. it is a sum of rank-1 psd Hermitian tensors. This paper studies how to detect the separability of Hermitian tensors. It is equivalent to the long-standing quantum separability problem in quantum physics, which asks to tell if a … Witrynarecovery via a novel factorization strategy 张立平 清华大学 03:30-04:00 Low-rank Tensor Train Decomposition Using Tensor Sketch ... 摘 要:In this talk, I will first report our result on dual quaternion Hermitian matrices. We showed that an n x n dual quaternion Hermitian matrix has exactly n eigenvalues,

The program I provided in my post uses the function cusolverDnCheevd which is based on LAPACK. LAPACK doc tells that it uses divide and conquer algorithm to solve Hermitian matrix. WitrynaHermitian tensors are generalizations of Hermitian matrices, but they have very different properties. Every complex Hermitian tensor is a sum of complex Hermitian rank-1 tensors. However, this is not true for the real case. We study basic properties for Hermitian tensors, such as Hermitian decompositions and Hermitian ranks. For …
