On the fine spectra of the Jacobi matrices on ????, ??, ???? (?? ≤ ?? ≤ ∞) and ?????? (?? ≤ ?? < ∞)

The spectrum and spectral divisions of band matrices are very new and popular topics of studies. In this paper, our aims are to investigate boundedness of Jacobi matrix which is a band matrix has important role in physics and give subdivisions of the spectra, which are approximate point spectrum, defect spectrum and compression spectrum, for a special type Jacobi matrix. Moreover, we will find the fine division of spectrum which is given by Goldberg with the help of it.
