What reading level is On Two Conjectures Regarding Eigenvalue Perturbations And a Common Counterexampl book?
To quickly assess the difficulty of the text, read a short excerpt:
The proof is a simple computation.
-1 -B -B 2 -1 -B -1 I ■ i) ■ ; . .
L0 = II* 1 ! I - 1 _ -1 /. ' -1 B - 1 1+X 1-1 » 1 -fl 2 (1+ ^ 2 ) 2-v3/2 -1 -fl -1 ■ -B" -1 -B -1 for fi»l. When X = i>#0, a mta (A-/|fc/) = ||(A-/m. /)-'||-' : (l + «p. ) 3 |n|fl 2 which as a function of n, reaches its minimum 3 3/2 / (2 fl 2 ) at ji = 2 _1/2 . If we let A be n by n and of the same structure as before: A = then o- min (A) ~ B ' as before and o- min (A-i>/) achieves its minimum 0(S' ") for \l ...= 0(\). Thus for large B and/or large n, using Conjectures 1 and 2 as computational heuristics can lead to very bad results.
Note however that the matrix A is quite special: not only is it defective but it is nearly derogatory. Of course perturbing A slightly would yield a matrix with distinct eigenvalues with similarly shaped S(A, (. ), so defectiveness per se is not essential, but nearness to a defective and derogatory matrix.
