Structured matrix factorization length

Jeong-Hoon Ju, Taehyeong Kim

Every (resp. a generic) complex $n \times n$ matrix can be expressed as a product of $2 n + 5$ (resp. $⌊ n /2 ⌋ + 1$ ) Toeplitz matrices. Motivated by this result, it is natu…

The border rank of the $4 \times 4$ determinant tensor is twelve

Jong In Han, Jeong-Hoon Ju, Yeongrak Kim

We show that the border rank of the $4 \times 4$ determinant tensor is at least $12$ over $C$ , using the fixed ideal theorem introduced by Buczyńska-Buczyński and the meth…
