A unique positive solution to a system of semilinear elliptic
equations
We study a system of semilinear elliptic equations that arises
from a predator-prey model. Previous related work proved the
existence of a unique positive solution to this system of
equations in the special case in which the parameter $\alpha=0$ in
this system of equations, provided that a positive parameter
$\kappa$ in this system of equations is sufficiently large. We
prove the existence of a unique positive solution to this system
of equations for any $\alpha \geq 0$ and for any $\kappa>0$.
