### Wikipedia

eigenvalue

In linear algebra, an eigenvector () or characteristic vector of a linear transformation is a nonzero vector that changes at most by a scalar factor when that linear transformation is applied to it. The corresponding eigenvalue, often denoted by λ {\displaystyle \lambda } , is the factor by which the eigenvector is scaled. Geometrically, an eigenvector, corresponding to a real nonzero eigenvalue, points in a direction in which it is stretched by the transformation and the eigenvalue is the factor by which it is stretched. If the eigenvalue is negative, the direction is reversed. Loosely speaking, in a multidimensional vector space, the eigenvector is not rotated.

### ChatGPT

eigenvalue

An eigenvalue is a scalar associated with a linear system of equations (i.e., a matrix), which characterizes the magnitude by which an associated vector, called an eigenvector, is scaled during a linear transformation represented by the matrix. In other words, if applying a matrix transformation to an eigenvector only changes the scale of the eigenvector, and not its direction, then the scale factor is the eigenvalue.
