摘要
Considering the most general one-species reaction-diffusion processes on a Cayley tree, it has been shown that there exist two integrable models. In the first model, the reactions are the various creation processes. i e circle circle -> center dot circle, circle circle -> center dot center dot and circle center dot -> center dot center dot, and in the second model, only the diffusion process center dot circle -> circle center dot exists For the first model, the probabilities P-1(m, t), of finding in particles on the 1th shell of the Cayley tree, have been found exactly, and for the second model, the functions P-1(1, t) have been calculated It has been shown that these are the only integrable models if one restricts consideration to the L + 1-shell probabilities P(m(0), m(1),...
