On close eigenvalues of tridiagonal matrices
Numerische Mathematik, 1995A symmetric tridiagonal matrix with a multiple eigenvalue must have a zero subdiagonal element \(\beta_i\) and must be a direct sum of two complementary blocks, both of which have the eigenvalue. Yet it is well known that a small spectral gap does not necessarily imply that some \(\beta_i\) is small, as is demonstrated by the Wilkinson matrix.
