Spectral attributes of self-adjoint fredholm operators in hilbert space: a rudimentary insight
In defining the finiteness or infiniteness conditions of discrete spectrum of the Schrodinger operators, a fundamental understanding on n(1 , F(·)) is crucial, where n(1, F) is the number of eigenvalues of the Fredholm operator F to the right of 1. Driven by this idea, this paper provided the invert...
