The second expansion of large solutions for semilinear elliptic equations Original Research Article

In this paper, we analyze the influence of the domain geometry in the second expansion of solutions to the boundary blow-up elliptic problem View the MathML source△u=b(x)f(u),u>0,x∈Ω,u|∂Ω=∞, where ΩΩ is a bounded domain with C4C4-smooth boundary in RNRN, View the MathML sourceb∈Cα(Ω̄) which is positive in ΩΩ and may be vanishing on the boundary, and ff is normalized regularly varying at infinity with index pp (p>1p>1).
