On the fine spectrum of the operator $B(r,s,t)$ over the sequence spaces $\ell_p$ and $bv_p$,($1<p<\infty$).
(English)
[J] Comput. Math. Appl. 60, No. 7, 2141-2152 (2010). ISSN 0898-1221

The authors determine the exact location of the fine spectrum of a linear operator given by an infinite three-diagonal banded matrix in the sequence spaces $\ell_p$ and $bv_p$ for $p\in(1,\infty)$. Their results generalize some earlier results of the authors and their collaborators on this subject.
