Abstract

Mathematics Physical Sciences Science & Technology
Let Delta(a, b) denote an infinite lower triangular double-band matrix. In this paper, the spectrum, the point spectrum, the continuous spectrum and the residual spectrum of the matrix Delta(a, b) as a linear operator on the sequence space l(p), where 1 <= p < infinity are characterized completely.
