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

Higher order natural differential operators on riemann surfaces

Complex Variables, Theory and Application: An International Journal, 1992
In this paper we continue the study of the elliptic differential operators with constant coefticients on two-dimensional domains, z=x+iy, in a Mobius or projectively invariant setting initiated in |5|. In particular we propose to study these operators in the general context of sheaf cohomology.

The self-adjointness conditions for a higher order differential operator with an operator coefficient

Mathematical Notes of the Academy of Sciences of the USSR, 1969
Certain sufficient conditions are found for self-adjointness of the differential operator generated by the expressionl (y)=(−1)ny2n +Q (x)y, −∞
