For any n≥ 2, Ω⊂ R n, and any given convex and coercive Hamiltonian function H∈ C 0 (R n), we find an optimal sufficient condition on H, that is, for any c∈ R, the level set H− 1 (c) does not contain any line segment, such then any absolute minimizer u∈ A M H (Ω) enjoys the linear approximation property. As consequences, we show that when n= 2, if u∈ A M H (Ω) then u∈ C 1; and if u∈ A M H (R 2) satisfies a linear growth at the infinity, then u is a linear function on R 2. In particular, if H is a strictly convex Banach norm‖⋅‖ on R 2, eg the l α-norm for 1< α<∞, then any u∈ A M H (Ω) is C 1. The ideas of proof are, instead of PDE approaches, purely variational and geometric.
