Abstract
Physical-region constraints on the low partial waves of scattering are derived on the basis of analyticity, crossing, and positivity of the absorptive parts. These constraints are sensitive only to the low-energy behavior of the partial-wave amplitudes. The necessity for subtractions in the dispersion relations implies that no results can be obtained for and waves.
