| Abstract: |
| We investigate the dynamics of two extensive classes of recursive sequences:$$x_{n 1}={c\sum\limits_{j=0}^{k}\sum\limits_{( i_0,i_1,\ldots, i_{2j})\in A_{2j}}x_{n-i_0}x_{n-i_1}\cdots x_{n-i_{2j}} f(x_{n-i_0}, x_{n-i_1}, \ldots, x_{n-i_{2k}})\over c\sum\limits_{j=1}^{k}\sum\limits_{( i_0,i_1,\ldots, i_{2j-1})\in A_{2j-1}}x_{n-i_0}x_{n-i_1}\cdots x_{n-i_{2j-1}} c f(x_{n-i_0}, x_{n-i_1}, \ldots, x_{n-i_{2k}})},$$ and $$x_{n 1}={c\sum\limits_{j=1}^{k}\sum\limits_{( i_0, i_1,\ldots, i_{2j-1})\in A_{2j-1}}x_{n-i_0}x_{n-i_1}\cdots x_{n-i_{2j-1}} c f(x_{n-i_0}, x_{n-i_1}, \ldots, x_{n-i_{2k}})\over c\sum\limits_{j=0}^{k}\sum\limits_{( i_0, i_1,\ldots, i_{2j})\in A_{2j}}x_{n-i_0}x_{n-i_1}\cdots x_{n-i_{2j}} f(x_{n-i_0}, x_{n-i_1}, \ldots, x_{n-i_{2k}})}.$$ We prove that their unique positive equilibrium $\overline{x} =1$ is globally asymptotically stable. And a new access is presented to study the theory of recursive sequences. |
