Integral matrices as diagonal quadratic forms

Jungin Lee

In this paper, we investigate the conditions under which a diagonal quadratic form $\sum_{i = 1}^{m} a_{i} X_{i}^{2}$ represents every $n \times n$ integral matrix, where $a_{i}$ ($1 \leq i \…

On a sum of positive rational numbers whose product is 1

Jungin Lee

In this note, we prove that for every two positive integers $m \geq n \geq 9$ , there exist $n$ positive rational numbers whose product is 1 and sum is $m$ .
