摘要

我们证明了对称帕斯卡三角形矩阵 modulo 2 具有这样的性质，即位于上边界或左边界的每个正方形子矩阵的行列式，在 ${\mathbb {Z}}$ 中计算，都等于 1 或 $-1$。此外，我们还给出了在具有有限单元组的交换环上帕斯卡样（n 次 m\ ）矩阵的确切数目。

On determinants of matrices related to Pascal’s triangle

We prove that the symmetric Pascal triangle matrix modulo 2 has the property that each of the square sub-matrices positioned at the upper border or on the left border has determinant, computed in ${\mathbb {Z}}$, equal to 1 or $-1$. Furthermore, we give the exact number of Pascal-like $n \times m$ matrices over a commutative ring with finite group of units.
