Abstract

The paper initiates the concept of negative definite consistent in Fredholm. The entanglement stability and the weakly entanglement stability of negative definite consistent in Fredholm for the system of 2×2 upper triangular operator matrices are characterized with the help of the negative definite consistent in Fredholm spectrum.
