What is the importance of eigenvalues/eigenvectors?
8 Eigenvalues and eigenvectors are central to the definition of measurement in quantum mechanics Measurements are what you do during experiments, so this is obviously of central importance to a Physics subject. The state of a system is a vector in Hilbert space, an infinite dimensional space square integrable functions.

How to intuitively understand eigenvalue and eigenvector?
Eigenvalues and eigenvectors are easy to calculate and the concept is not difficult to understand. I found that there are many applications of eigenvalues and eigenvectors in multivariate analysis.

Do non-square matrices have eigenvalues? - Mathematics Stack Exchange
Non-square matrices do not have eigenvalues. If the matrix X is a real matrix, the eigenvalues will either be all real, or else there will be complex conjugate pairs.

All tricks to find eigenvalues in $3\times 3$ in a faster way?
The fastest way to compute the eigenvalues in this case is to recognize that this matrix is a rank 1 update of a multiple of the identity matrix.

What are the Eigenvalues of $A^2?$ - Mathematics Stack Exchange
I got your point. while in that we can modify this question for a 4×4 matrix with A has eigen value 1,1,1,2 . Then can it be possible to have 1,4,3,1/3. this time (det A)^2= (det A^2) satisfied.

What is the relation between rank of a matrix, its eigenvalues and ...
1) If a matrix has 1 eigenvalue as zero, the dimension of its kernel may be 1 or more (depends upon the number of other eigenvalues). 2) If it has n distinct eigenvalues its rank is atleast n.

linear algebra - Invertibility, eigenvalues and singular values ...
15 I am confused about the relationship between the invertibility of a matrix and its eigenvalues. What do the eigenvalues of a matrix tell you about whether a matrix is invertible or not? Also, what about the "singular values" of a matrix? If there are good online resources which answer these question I would be grateful for any pointers.
