On the fine spectrum of generalized upper triangular triple-band matrices (Δ2uvw)t over the sequence space l1
Keyword(s):
In this work, we determine the fine spectrum of the matrix operator (?2uvw)t which is defined generalized upper triangular triple band matrix on l1. Also, we give the approximate point spectrum, defect spectrum and compression spectrum of the matrix operator (?2uvw)t on l1.
