Two iterative formulas of largest and smallest singular value of nonsingular matrices

Shun Xu

We obtain an iterative formula that converges incrementally to the smallest singular value. Similarly, we obtain an iterative formula that converges decreasingly to the largest sin…

In this paper, we give a complete classification of $n$ -dimensional nilpotent non-Tortkara anticommutative algebras with $(n - 4)$ -dimensional annihilator over $C$ .
