In this paper, we are interested in the existence result of solutions for the nonlinear Dirichlet problem of the type:
$$\begin{aligned} \left\{ \begin{aligned}&-\mathrm{div} (M(x) \nabla u )+ \gamma u^p= B \frac{|\nabla u|^q}{u^\theta }+f\ \ \mathrm{in}\ \Omega ,\\&u> 0\ \ \mathrm{in}\ \Omega ,\\&u=0\ \ \mathrm{on}\ {\partial \Omega },\\ \end{aligned} \right. \end{aligned}$$where \(\Omega \) is a bounded open subset of \(\mathbb {R}^N\), \(N>2\), M(x) is a uniformly elliptic and bounded matrix, \(\gamma > 0\), \(B> 0\), \(1\le q<2\), \(0<\theta \le 1\), and the source f is a nonnegative (not identically zero) function belonging to \(L^1(\Omega )\).

在本文中,我们对以下类型的非线性Dirichlet问题的解的存在结果感兴趣:
$$ \ begin {aligned} \ left \ {\ begin {aligned}&-\ mathrm {div}(M(x)\ nabla u)+ \ gamma u ^ p = B \ frac {| \ nabla u | ^ q } {u ^ \ theta} + f \ \ \ mathrm {in} \ \ Omega,\\&u> 0 \ \ \ mathrm {in} \ \ Omega,\\&u = 0 \ \ \ mathrm {on} \ { \ partial \ Omega},\\ \ end {aligned} \ right。\ end {aligned} $$其中\(\ Omega \)是\(\ mathbb {R} ^ N \)的有界开放子集,\(N> 2 \),M(x)是一个均匀椭圆和有界矩阵,\(\ gamma> 0 \),\(B> 0 \),\(1 \ le q <2 \),\(0 <\ theta \ le 1 \),并且源f是属于的非负(不完全为零)函数\(L ^ 1(\ Omega)\)。
