Spectra and fine spectra for the upper triangular band matrix U (a 0 , a 1 , a 2 ; b 0 , b 1 , b 2 ) over the sequence space c 0
The aim of this paper is to obtain the spectrum, fine spectrum, approximate point spectrum, defect spectrum and compression spectrum of the operator on the sequence space c 0 where b 0 , b 1 , b 2 are nonrzero and the ... 
Subdivision of the spectra for difference operator over certain sequence space
Basar F.; Durna N.; Yildirim M. (2012)In a series of papers, B. Altay, F. Basar and A. M. Akhmedov recently investigated the spectra and fine spectra for difference operator, considered as bounded operator over various sequence spaces. In the present paper ... 
Subdivision of the spectra for factorable matrices on c and ? p
Durna N.; Yildirim M. (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. ... 
Subdivision of the spectra for factorable matrices on c0
Durna N.; Yildirim M. (2011)In a series of papers, B.E. Rhoades and M. Yildirim previously investigated the spectra and fine spectra for factorable matrices, considered as bounded operators over various sequence spaces. In the present paper approximation ... 
Subdivisions of the spectra for generalized difference operator ? ? on the sequence space ? 1
Başar F.; Durna N.; Yildirim M. (International Conference on Mathematical Science, ICMS, 2010)The fine spectrum of the generalized difference operator ? ? defined by a strictly decreasing sequence ? of positive reals on the space ? 1 has been studied by Srivastava and Kumar [Thai J. Math. 8(2)(2010), 719]. Following ... 
Subdivisions of the spectra for generalized difference operator over certain sequence spaces
Başar F.; Durna N.; Yildirim M. (2011)The fine spectrum of the generalized difference operator B(r, s) represented by a double band matrix over the sequence spaces c0 and c was studied by Altay and Başar [B. Altay, F. Başar, On the fine spectrum of the generalized ... 
Subdi{dotless}vi{dotless}si{dotless}ons of the spectra for cesaro, rhaly and weighted mean operators on c0,c and ?p
Amirov R.K.; Durna N.; Yildirim M. (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 this study, the relationship between the ...
