We consider a two-species reaction-diffusion (RD) system. Both "fluxes" contain the gradients of both unknown solutions. We show that-for some parameter range- there exist two different type of periodic stationary solutions. Using them, we are able to divide into parts the (eight-dimensional) parameter space and indicate the so called Turing domains where our solutions exist. The boundaries of these domains, in analogy with "bifurcation point", called "bifurcation surfaces". As it is commonly believed, these solutions are limits as t goes to infinity of the solutions of corresponding evolution system. In a forthcoming paper we shall give a detailed account about our numerical results concerning different kind of stability. Here we also show some numerical calculations making plausible that our solutions are in fact attractors with a large domain of attraction in the space of initial functions.}, keywords = {pattern formation; Periodic stationary solutions; Stability of patterns; Cross-diffusion; Reaction-diffusion (RD )systems}, year = {2022}, eissn = {1579-1505} } @article{MTMT:31891062, title = {Reply to comment on ‘Heat conduction: a telegraph-type model with self-similar behavior of solutions’ (2010 J.
