 note = {For an energy operator H, which is any one of selfadjoint extensions of -(d/dx)² on an open interval I, we compute the reciprocal sum of the eigenvalues and examine how the sum depends on the parameters which determine selfadjoint extension. Given a momentum operator P, which is any one of selfadjoint extensions of -i(d/dx) on I, we find the parameters that satisfy P² = H in all possible energy operators.},
