摘要: This paper is mainly concerned with entire solutions of the following two-species Lotka-Volterra competition system with nonlocal (convolution) dispersals:Here $a\neq 1$, $b\neq1$, $d$, and $r$ are positive constants. By studying the eigenvalue problem of (0.1) linearized at $(\phi_c(\xi), 0)$, we construct a pair of super- and sub-solutions for (0.1), and then establish the existence of entire solutions originating from $(\phi_c(\xi), 0)$ as $t\rightarrow -\infty$, where $\phi_c$ denotes the traveling wave solution of the nonlocal Fisher-KPP equation $u_t=k*u-u+u\left(1-u\right)$. Moreover, we give a detailed description on the long-time behavior of such entire solutions as $t\rightarrow \infty$. Compared to the known works on the Lotka-Volterra competition system with classical diffusions, this paper overcomes many difficulties due to the appearance of nonlocal dispersal operators.
