Abstract:We consider singular differential operators of order 2m, m ∈ ?, with discrete spectrum in L 20, + ∞). For self-adjoint extensions given by the boundary conditions y(0) = y″(0) = ? = y (2m?2)(0) = 0 or y′(0) = y?(0) = ? = y (2m?1)(0) = 0, we obtain regularized traces. We present the explicit form of the spectral function, which can be used for calculating regularized traces.
