“…There are a lot of papers on qualitative behavior of solutions for evolution systems of reactiondiffusion type. It caused by the theoretical and applied significance of such objects [5,8,13,16,20]. The particular cases of reaction-diffusion problems are Kolmogorov -Petrovskiy -Piskunov equations (the problem on the gene diffusion) [9], models of Belousov -Zhabotinsky reaction [3,15], Gause -Vitta models [17,18], Selkov model for glycolysis [10,14] etc.…”
