Let H 0 be the mth power (m a positive integer) of the self-adjoint operator defined in the Hilbert space L2(0, π) by the differential operator — (d 2/dx 2) and the boundary conditions u(0) = u(π) = 0. The eigenvalues of H 0 are μn = n 2m and the corresponding eigenfunctions are ϕn = (2/π)1/2 sin nx, n = 1 , 2 , . . ..

Let p be a (2m — 2)-times continuously differentiate real valued function defined over the interval [0, π] satisfying the conditions p (j)(0) = p (j)(π) = 0 for j odd and less than 2m — 4.
