Spectral functions of the simplest even order ordinary differential operator (English)
0 references
Let \(A\) be the minimal operator generated in \(L^2(0,\infty )\) by the differential expression \((-1)^n\frac{d^{2n}}{dt^{2n}}\). The author finds explicitly the spetral functions and Weyl functions corresponding to the Friedrichs and Krein extensions of \(A\).
