In this paper, we consider the existence and concentration of positive
solutions of the Kirchhoff-type problem \[
\left\{ \begin{array}
[c]{ll}%
-\left(a+b\int_{\mathbb{R}^3}|\nabla
u|^2dx\right)\Delta
u+\lambda V(x)u=f(x,u)\text{,} &
\text{in
}\mathbb{R}^{3}\text{,}\\
u>0~~~~\text{in
}\mathbb{R}^{3}~~~~u\in
H^1(\mathbb{R}^3)\text{,}%
\end{array} % \right.
\] where $a,b>0$ are constants,
$\lambda>0$ is a parameter. Under some
suitable assumptions on $V$ and $f$, the existence and concentration
of positive solutions is obtained by using variational methods.
