On Higher-Order Differential Operators with Singularity inside the Interval

Mathematical Notes, 2002
Differential equations with singularities inside the interval arise in different areas of mathematics and in applications. A wide class of differential equations with turning points can be reduced to the equations considered by the author. This paper is concerned with the non-selfadjoint boundary value problem for the studied differential equation with

On higher-order differential operators with a singular point

Inverse Problems, 1993
The paper is concerned with a very specific inverse spectral problem. This problem is formulated as follows: Given the Weyl matrix \({\mathfrak M}(\lambda)\), construct a differential operator \(l\) associated with the higher-order differential equation \[ ly\equiv y^{(n)}+ \sum^{n- 2}_{j=0} \left({\nu_ j\over x^{n-j}}+ q_ j(x)\right) y^{(j)}=\lambda y\

Reconstruction of higher-order differential operators on compact graphs

Doklady Mathematics, 2008
In this paper, the author studies the inverse spectral problem for differential operators of any order on compact trees (i.e., on graphs without cycles). As the basis spectral characteristics, the author introduces and studies the Titchmarsh--Weyl matrices, which are a generalization of the Titchmarsh--Weyl functions (\(m\)-functions) for the classical

On higher-order differential operators with a regular singularity

Sbornik: Mathematics, 1995
Summary: A boundary-value problem for the non-self-adjoint differential operators \[ \ell y \equiv y^{(n)} + \sum^{n - 2}_{j = 0} \left( {\nu_j \over x^{n - j}} + q_j(x) \right) y^{(j)}, \quad 0 < x < T, \] with a regular singularity at zero is investigated.

Spectral Analysis of Higher-Order Differential Operators II: Fourth-Order Equations

Journal of the London Mathematical Society, 1999
Summary: The author investigates location and nature of the spectrum of the fourth-order selfadjoint equation \[ (p_0 y'')''+ (p_1 y')'+ qy= zwy \] subject to certain asymptotic assumptions on the coefficients. The main tools are the theory of asymptotic integration and the Titchmarsh-Weyl \(M\)-matrix.
