In this paper, some two-scale finite element discretizations are introduced and analyzed for a class of nonlinear elliptic eigenvalue problems on tensor product domains. It is shown that the solution obtained by the standard finite element method on a one-scale fine grid can be numerically replaced with a combination of some solutions on a coarse grid and some univariate fine grids by two-scale finite element discretizations. Compared with the standard finite element solution, the two-scale finite element approximations save computational cost significantly while achieving the same accuracy.
