The equation is, then, symmetrized so that it remains invariant under the change d going to -d, where d is the smallest span of time. This symmetric equation has solutions, which come in reciprocally related pairs. One member of a pair agrees with the classical solution and the other is an oscillating solution and does not converge to a limit as d goes to 0. This solution contributes to oscillator energy a term which is a multiple of half-integers.4 pagesGeneral PhysicsReciprocal Symmetry and Classical Discrete Oscillator Incorporating Half-Integral Energy Levelstext
