Sažetak

We consider the weighted anisotropic integral functional $$I(u)={\int }_{\mathrm{\Omega }}f(x,Du(x))dx,$$ where $\mathrm{\Omega }\subset R^n$ is a bounded open set, $u:\mathrm{\Omega }\subset R^n\to R$, $f:\mathrm{\Omega }\times R^n\to [0,+\mathrm{\infty })$ is a Carath\'{e}odory function satisfying$$\sum _{i=1}^n{v}_i{|z_i|}^{p_i}\le f(x,z)\le c(1+\sum _{i=1}^n{v}_i{|z_i|}^{q_i}),$$\in which $c>0$ is a constant, $1
