Goncalves and Santos [32] showed both the existence, uniqueness and boundary behavior of classical solutions and the nonexistence of weak solution to problem (1.1). Most recently, when g satisfies (g 1 )-(g 2 ), f satisfies (f 1 ), b, a satisfy (H 1 ), by establishing a local comparison principle of solutions near the boundary, Zhang et al [33] studied the first order expansion of classical solutions to problem (1.1), and they also showed the existence and nonexistence of classical solutions.…”

AbstractIn this paper, we mainly study the second order expansion of classical solutions in a neighborhoodwhere Ω is a bounded domain with smooth boundary in R N , λ ≥ 0. The weight functions b, a ∈ C α loc (Ω) are positive in Ω and both may be vanishing or be singular on the boundary. The function g ∈ C 1 ((0, ∞), (0, ∞)) satisfies lim t→0 + g(t) = ∞, and f ∈ C([0, ∞), [0, ∞)). We show that the nonlinear term λa(x)f (u) does not affect the second order expansion of solutions in a neighborhood of ∂Ω to the problem for some kinds of functions b and a.

In this paper we study existence and multiplicity of weak solutions of the homogenous Dirichlet problem for a singular semilinear elliptic equation with a quadratic gradient term. The proofs for the main results are based on a priori estimates of solutions of approximate problems.
