Spectral functions of the simplest even order ordinary differential operator

     Article (.pdf)

Abstract

We consider the minimal differential operator $A$ generated in $L^2(0,\infty)$ by the differential expression $l(y) = (-1)^n y^{(2n)}$. Using the technique of boundary triplets and the corresponding Weyl functions, we find explicit form of the characteristic matrix and the corresponding spectral function for the Friedrichs and Krein extensions of the operator $A$.

Key words: Friedrichs and Krein extensions, spectral function, boundary triplet, Weyl function, Vandermonde determinant.
