“…Finally, in two‐dimensional reaction–diffusion systems, it is common to observe patterns that help illuminate the dynamics on the studied phenomenon. Examples of typical patterns can arise from Turing instabilities (Li, ; Sun, Jusup, Jin, Wang, & Wang, ), Turing–Hopf bifurcations (Castillo, Sánchez‐Garduño, & Padilla, ), wave splitting (Petrov, Scott, & Showalter, ), and spiral waves (Olmos‐Liceaga, ). Currently, propagation of the species with periodic invasions, given by spiral wave structures (Olmos‐Liceaga, ), is being considered, as it is a straightforward direction to go when studying excitable systems.…”
