Let Ω be a bounded smooth domain in R N. Assume that 0< α< 2∗− 1 2, a> 0, and b> 0. We consider the following Dirichlet problem of Kirchhoff type equation (0.1)−(a+ b‖∇ u‖ 2 2 α) Δ u=| u| p− 1 u+ h (x, u,∇ u) in Ω, u= 0 on∂ Ω with p∈(0, 2∗)∖{1}. Where 2∗=+∞ for N= 2, and 2∗= N+ 2 N− 2 for N≥ 3. Under suitable conditions of h (x, u,∇ u)(see (A),(H 1) and (H 2) in Section 3), we get a priori estimates for positive solutions to problem (0.1). By making use of these estimates and the continuous method, we further get some existence results for positive solutions to problem (0.1) when 0< p< 1, or 2 α+ 1< p< 2∗. Effects of the term a+ b‖∇ u‖ 2 2 α on the solution set of problem (0.1) can be seen in an example given in Section 2.
