| Nov 25, 2011 at 16:14 | comment | added | kassabov | your result is equivalent to the following: a small petrubation of a single jordan block is a sum of jordan blocks with different eigenvalues. This follows form the fact that rank of $J - \lambda I$ is $ > n-1$ and and the "norm" of the operator is large, i.e., a small pertrubation will not decrease the rank. | |
