This expansion formula shows the singularity profile of solutions at the boundary. We deal with both linear and nonlinear elliptic equations, including fully nonlinear elliptic equations and equations of Monge-Ampère type.National Natural Science Foundation of China (Grant Nos. 11771237 and 11871432).application/pdfen-AUboundary asymptotic expansionsingular nonlinear elliptic equationsDirichlet problem202110.1007/s11425-020-1822-92021-12-19
