Abstract:

This paper dealt with the uniqueness of positive stationary solutions for Sel’kov model with Neumann boundary conditions. Firstly, we  established a new integral identity, which proved that there was only one positive solution to the problem for 0<p≤1. Secondly, we discussed the uniqueness of positive solutions for the problem with p>1 by means of a priori estimate technique.

Key words: Sel’kov model, positive stationary solution, uniqueness
