Abstract: | The asymptotic behavior of the solutions of three classes of reaction-diffusion systems with homogeneous Neumann boundary condition arising from gas-liquid aborption, in chemical diffusion processes and combusition theory, and in bacteriology were analysed in greater detail in Rocky Mountain J. Math., 12(1982), 55-73, J. Math. Anal. Appl., 82 (1981 ), 503-526 and J.Math. Anal. Appl., 108 (1985), 1-14. But, some conclusions in those pepers are incorrect and some atgurnents are arses on several wrong prerequisites. It is the aim of the prement poper that is to clarify some facts, reprove some theorems, generalize and improve some results of those papers. |
