Sažetak

We consider the weighted anisotropic integral functional $$I(u)=\int_{\Omega}f(x,Du(x))dx,$$ where $\Omega\subset R^n$ is a bounded open set, $u:\Omega\subset R^n \rightarrow R $, $f:\Omega \times R^n \rightarrow [0,+\infty) $ is a Carath\'{e}odory function satisfying$$ \sum_{i=1}^{n}v_{i}{|z_{i}|}^{p_{i}}\leq f(x,z)\leq c\left(1+\sum_{i=1}^{n}v_{i}{|z_{i}|}^{q_{i}}\right),$$\\in which $c>0 $ is a constant, $1
