Query: Asymptotic expansion and optimal symmetry of minimal gradient graph
  equations in dimension 2   In this paper, we study asymptotic expansion at infinity and symmetry of zero
mean curvature equations of gradient graph in dimension 2, which include the
Monge--Amp\`ere equation, inverse harmonic Hessian equation and the special
Lagrangian equation. This refines the research of asymptotic behavior, gives
the precise gap between exterior minimal gradient graph and the entire case,
and extends the classification results of Monge--Amp\`ere equations.
