Spectral Analysis of Boundary Value Problems with Retarded Argument
Şen, Erdoğan; Bayramov, Azad (Ankara Univ, Fac Sci, 2017)In this paper, by modifying some techniques of [S.B. Norkin, Differential equations of the second order with retarded argument, Translations of Mathematical Monographs, Vol. 31, AMS, Providence, RI, 1972] and suggesting ... -
Spectral Analysis of Discontinuous Boundary-Value Problems with Retarded Argument
Şen, Erdoğan (B Verkin Inst Low Temperature Physics & Engineering, 2018)In the paper, we are concerned with spectral properties of discontinuous Sturm-Liouville type problems with retarded argument. We extend and generalize some approaches and results of the classical regular and discontinuous ... -
Spectral Problem for the Sturm-Liouville Operator with Retarded Argument Containing a Spectral Parameter in the Boundary Condition
Şen, Erdoğan; Açıkgöz, Mehmet; Aracı, Serkan (Springer, 2017)We consider a discontinuous Sturm-Liouville problem with retarded argument containing a spectral parameter in the boundary condition. First, we investigate the simplicity of eigenvalues and then prove the existence theorem. ... -
Spectral properties of boundary-value-transmission problems with a constant retarded argument
Şen, Erdoğan (TUBITAK, 2019)In this work, spectra and asymptotics of eigenfunctions of a generalized class of boundary value problems with constant retarded argument are obtained. Contrary to previous works in the literature, the problem has nonclassical ... -
Spectral Properties of Discontinuous Sturm-Liouville Problems with a Finite Number of Transmission Conditions
Şen, Erdoğan; Mukhtarov, O. (Springer Basel Ag, 2016)In this paper we investigate discontinuous two-point boundary value problems with eigenparameter in the boundary conditions and with transmission conditions at the finitely many points of discontinuity. A self-adjoint ... -
Spectrum, trace and nodal points of a sturm-liouville type delayed differential operator with interface conditions
Şen, Erdoğan (Rocky Mountain Mathematics Consortium, 2021)A formula for regularized sums of eigenvalues of a Sturm–Liouville problem with delayed argument at the point of discontinuity is obtained. Moreover, nodal points of the related problem are investigated. © Rocky Mountain ... -
A Sturm-Liouville problem with a discontinuous coefficient and containing an eigenparameter in the boundary condition
Şen, Erdoğan (2013)We study a Sturm-Liouville operator with eigenparameter-dependent boundary conditions and transmission conditions at two interior points. We give an operator-theoretic formulation, construct fundamental solutions, investigate ... -
Sturm-Liouville Problems with Retarded Argument and A Finite Number of Transmission Conditions
Şen, Erdoğan (Texas State Univ, 2017)The main goal of the present paper is to study the asymptotic behaviour of eigenvalues and eigenfunctions of a discontinuous boundary-value problem with retarded argument with a finite number of transmission conditions. -
