Fine Spectra of Upper Triangular Double - Band Matrices over the Sequence Space p , 1 < p < ∞
The operator A r̃, s̃ on sequence space on p is defined A r̃, s̃ x rkxk skxk 1 ∞ k 0, where x xk ∈ p, and r̃ and s̃ are two convergent sequences of nonzero real numbers satisfying certain conditions, where 1 < p < ∞ . The main purpose of this paper is to determine the fine spectrum with respect to the Goldberg’s classification of the operator A r̃, s̃ defined by a double sequential band matrix over the...

The main purpose of this paper is to determine the fine spectrum of the generalized upper triangular double-band matrices uv over the sequence spaces c0 and c. These results are more general than the spectrum of upper triangular double-band matrices of Karakaya and Altun[V. Karakaya, M. Altun, Fine spectra of upper triangular doubleband matrices, Journal of Computational and Applied Mathematics...
متن کاملFine spectra of upper triangular double-band matrices
The fine spectra of lower triangular double-band matrices were examined by several authors. Here we determine the fine spectra of upper triangular double-band matrices over the sequence spaces () p and () bv p. Upper triangular double-band matrices are infinite matrices which include the left-shift, averaging and difference operators.
متن کاملOn the fine spectra of the generalized difference operator Delta_{uv} over the sequence space c0
The main purpose of this paper is to detemine the fine spectrum of the generalized difference operator Delta_{uv} over the sequence space c0. These results are more general than the fine spectrum of the generalized difference operator Delta_{uv} of Srivastava and Kumar.
متن کاملSpectra and fine spectra of certain lower triangular double-band matrices as operators
*Correspondence: [email protected] Mathematics Department, Faculty of Science, Damietta University, New Damietta, Egypt Abstract In this paper we determine the fine spectrum of the generalized difference operator a,b defined by a lower triangular double-band matrix over the sequence space c0. The class of the operator a,b contains as special cases many operators that have been studied recent...
