Multi-species reaction-diffusion systems, with
nearest-neighbor interaction on a one-dimensional lattice are
considered. Necessary and sufficient constraints on the
interaction rates are obtained, that guarantee the closedness of
the time evolution equation for 's, the
expectation value of the product of certain linear combination of
the number operators on n consecutive sites at time t. The
constraints are solved for the single-species left-right-symmetric
systems. Also, examples of multi-species system for which the
evolution equations of
's are closed, are
given.
