“…Therefore, it is of great significance to understand the cause and mechanism of pattern formation for revealing the mystery of nature formation. In order to understand its formation mechanism, many scholars turned their work to study various mathematical models with different factors, such as delay [14,16,36], noise [19], network [25,28,34], season [29] and so on, among which, the reactiondiffusion equation was often used in [1,22] and the references therein.…”
