Example 2: Check whether the given matrix is nilpotent or not.\( M=\begin{bmatrix}2&\ -2\\2&\ -2\end{bmatrix} \).

i We describe nonempty intersections of B with nilpotent orbits in the case the nn matrix B has rank n2. t S is nilpotent if there is The eigenvalues of a nilpotent matrix are zero. {\displaystyle {\mathfrak {p}}\cap S=\emptyset } Thus, a linear map is nilpotent iff it has a nilpotent matrix in some basis.

Here, let us calculate the square of the matrix, \( A^2=\begin{bmatrix}2;\ -4\\ 1;\ -2\end{bmatrix}\begin{bmatrix}2;\ -4\\ 1;\ -2\end{bmatrix}=\begin{bmatrix}\left(2\times1\right)+\left(-4\times1\right)&\ \ \left(2\times-4\right)+\left(-4\times-2\right)\\ \left(1\times2\right)+\left(-2\times1\right);\ \ \left(1\times-4\right)+\left(-2\times-2\right)\end{bmatrix}=\begin{bmatrix}0;0\\ 0;0\end{bmatrix} \). Nilpotent matrix is a square matrix which means it has an equal number of rows and columns and it satisfies the condition of matrix multiplication. Baba will be missed by all who knew her.
