On the fine spectrum of the operator B(r, s, t) over the sequence spaces ℓ1 and bv
We determine the fine spectrum of the operator B(r,s,t) defined by a band matrix over the sequence spaces @?"1 and bv. This generalizes the spectrum of the second order difference operator @D^2 andExpand

INFINITE MATRICES AND σ(A)-CORE
In [8], the concepts of a-core of a bounded number sequence x have been introduced and also some inequalities which are analogues of Knopp's core theorem have been proved. In this paper, using theExpand
