Abstract
The Schlosser-Marcus stationary principle for discontinuous approximate wave functions is shown to be the "finite part" of the energy expectation value. The divergent terms in the expectation value of the kinetic energy are second order in the discontinuity, which explains why the energy expression obtained when they are omitted remains stationary.Keywords
