Then using these asymptotic formulas, we find necessary and sufficient conditions on the coefficients for which the system of eigenfunctions and associated functions of the operator under consideration forms a Riesz basis. en_US dc.language.iso eng en_US dc.publisher Springer Verlag en_US dc.relation.isversionof 10.2478/s11533-011-0015-1 en_US dc.rights info:eu-repo/semantics/closedAccess en_US dc.subject Differential Operators en_US dc.subject Eigenfunction Expansion en_US dc.subject Ordinary Differential Equations en_US dc.title On the basis property of the root functions of differential operators with matrix coefficients en_US dc.type article en_US dc.relation.journal Central European Journal of Mathematics en_US dc.contributor.department Doğuş Üniversitesi, Fen Edebiyat Fakültesi, Matematik Bölümü en_US dc.contributor.authorID TR55504 en_US dc.identifier.volume 9 en_US dc.identifier.issue 3 en_US dc.identifier.startpage 657 en_US dc.identifier.endpage 672 en_US
