Existence of non-negative solutions for predator-prey elliptic systems with a sign-changing nonlinearity

By the method of monotone iteration and Schauder fixed point theorem, we prove the existence of non-negative solutions to the system $$displaylines{ -Delta u= lambda a(x) f(v)quad hbox{in }Omega,cr -Delta v= lambda b(x) g(u)quad hbox{in } Omega,cr u =v=0quad hbox{on }partial Omega, }$$ for $l...
