Recently. the Lanczos bidiagonalization method over tensor space has been proposed for computing the maximum and minimum singular values of a tensor sum T. The method over tensor space is practical in memory and has a simple implementation due to recent developments in tensor computations; however. there is still room for improvement in the convergence to the minimum singular value. https://www.bekindtopets.com/mega-super-Paint-Splatter-Purple-iPad-Pro-12-9in-2020-Clear-Case-p23822-must-buy/
