摘要: 考慮一類齊次Dirichlet邊界條件下具有非線性交叉擴(kuò)散的B-D型捕食-食餌系統(tǒng)的穩(wěn)態(tài)解. 首先, 根據(jù)線性算子的譜理論分析平凡解和半平凡解的穩(wěn)定性; 其次, 利用正錐中的不動(dòng)點(diǎn)指數(shù)理論給出共存解存在的充分條件.

關(guān)鍵詞: 捕食-食餌系統(tǒng); B-D反應(yīng)函數(shù); 穩(wěn)定性; 共存解

Coexistence Solutions of B-D Type Predator-PreySystem with Nonlinear Cross-Diffusion

CUI Lu, LI Shanbing

(College of Mathematics and Statistics, Xidian University, Xi’an 710126, China)

Abstract: We considered the steady-state solutions of a B-D type predator-prey system with nonlinear cross-diffusion under homogeneous Dirichlet boundary conditions. Firstly, we analyzed the stability of trivial solution and semi-trivial solutions based on the spectral theory of linear operators. Secondly, the sufficient conditions for the existence of coexistence solutions were obtained by using the fixed point index theory in positive cones.

Keywords: predator-prey system; B-D type response function; stability; coexistence solution
