Abstract : The approximation properties for $L^2$-projection, Raviart-Thomas projection, and inverse inequality have been derived in $3$ dimensional space. $h$-$p$-mixed finite element methods for strongly nonlinear second order elliptic problems are proposed and analyzed in $3D$. Solvability and convergence of the linearized problem have been shown through duality argument and fixed point argument. The analysis is carried out in detail using Raviart-Thomas-Nedelec spaces as an example.
