Questions where the notion matrix has an important or crucial role (for the latter, note the tag matrix-theory for potential use). Matrices appear in various parts of mathematics, and this tag is typically combined with other tags to make the general subject clear, such as an appropriate top-level tag ra.rings-and-algebras, co.combinatorics, etc. and other tags that might be applicable. There are also several more specialized tags concerning matrices.

How one can show that this matrix is full rank?
Suppose to have the following matrices
$$N_{i,1}=\begin{pmatrix}
1 & 0 \\
e_{i,1} & 1
\end{pmatrix}$$
$$N_{i,2}=\begin{pmatrix}
(-1)^de_{d-1} & (-1)^{d-1}e_{d-2} & \cdots & (-1)^2e_1 \\
0 & (-1)^de_{d- … Since the matrices $S_i$ are a little bit hard to understand, I write them here in the cases $d=3,4,5,6$. …
