A note on the spectral assignment problem for operators
Ren Fang-guo · Basic Sciences Journal of Textile Universities · 2008
Let A,and B be given the operators with A,B acting on complex Hilbert spaces H and K,respectively.The spectral distribution of A+BF was mainly characterized by using the space decomposition,the construction technique in operator matrix and the mathematical induction when the pair operator(A,B) is admissible and R(B) is a close innite dimension subspace,where F∈B(H,K).
