Let QN be an N-anisotropic Laplacian operator, which contains the ordinary Laplacian operator,N-Laplacian operator and the anisotropic Laplacian operator. We firstly obtain the properties of QN, which contain the weak maximal principle, the comparison principle and the mean value property. Then a priori estimates and blow-up analysis for solutions of-QNu = Veu in bounded domain in RN, N≥2 are established.Finally, the blow-up behavior of the only singular point is also considered.
