## Existence results of positive solutions of Kirchhoff type problems.(English)Zbl 1175.35038

Summary: In the present paper, we use variational methods to prove two existence results of positive solutions of the following Kirchhoff type problems
\begin{aligned} -\bigg(a+b \int_\Omega |\nabla u|^2\bigg) \Delta u=f(x,u), &\quad\text{in }\Omega;\\ u=0, &\quad\text{on }\partial\Omega. \end{aligned}
One deals with the asymptotic behaviors of $$f$$ near zero and infinity and the other deals with 4-superlinear of $$f$$ at infinity.
