Relativistic, fixed momentum-transfer dispersion relations are derived (but not proved) for pion scattering from SIGMA and LAMBDA particles and the processes pi + LAMBDA in equilibrium pi + SIGMA . Separate equations for the S- and P-wave amplitudes are obtained under the assumptions that high- energy processes and baryon recoil may be neglected. The P-wave equations are identical to those derived from Chew-Low theory for these processes. A brief discussion is given of the behavior of the P-wave amplitudes under the assumption of global symmetry. It is pointed out that the production of K--N pairs may play an innportant role in both the S- and P-wave equations. (auth)
