SPECTRA AND FINE SPECTRA OF THE UPPER TRIANGULAR BAND MATRIX U(a; 0; b) OVER THE SEQUENCE SPACE C-0
Abstract
The aim of this paper is to obtain the spectrum, fine spectrum, approximate point spectrum, defect spectrum and compression spectrum of the operator U(a;0;b) = [GRAPHICS] (b(0) , b(1) , b(2) not equal 0) on the sequence space c(0) where the non-zero diagonals are the entries of an oscillatory sequence.

SUBDIVISIONS OF THE SPECTRA FOR GENERALIZED DIFFERENCE OPERATOR C-nu ON THE SEQUENCE SPACE l(1)
Basar, Feyzi; Durna, Nuh; Yildirim, Mustafa (AMER INST PHYSICS, 2010)The fine spectrum of the generalized difference operator C-nu defined by a strictly decreasing sequence nu of positive reels on the space l(1) has been studied by Srivastava and Kumar [Thai J. Math. 8(2)(2010), 7-19]. ... -
Subdivision of the spectra for factorable matrices on c and l(p)
Durna, Nuh; Yildirim, Mustafa (UNIV OSIJEK, DEPT MATHEMATICS, 2011)There are many different ways to subdivide the spectrum of a bounded linear operator; some of them are motivated by applications to physics (in particular, quantum mechanics). In a series of papers, B.E. Rhoades and M. ... -
