Abstract
The strip approximation to the Mandelstam representation is applied to the Π-N problem, and the basic equations given. The asymptotic behavior of the invariant amplitudes in the physical regions is discussed in terms of the unitarity condition on partial-wave amplitudes, the constancy of high-energy scattering cross sections, and the Pomeranchuk theorem, and it is shown to imply that no subtractions should be necessary except in the J=½ wave of the Π-N channel and the J=0 wave of the Π+Π→N+N̅ channel. This obviates the difficulties encountered by earlier workers when they subtracted higher waves.
