As nouns the difference between eigenvalue and eigenspectrum

is that eigenvalue is a scalar, $\backslash lambda\backslash !$, such that there exists a vector $x$ (the corresponding eigenvector) for which the of $x$ under a given linear operator $\backslash rm\; A\backslash !$ is equal to the of $x$ under multiplication by $\backslash lambda$; i.e. $\{\backslash rm\; A\}\; x\; =\; \backslash lambda\; x\backslash !$eigenspectrum is a spectrum of eigenvalues.
