TY - JOUR T1 - Semilinear Elliptic Equations with Singularity on the Boundary JO - Journal of Partial Differential Equations VL - 1 SP - 28 EP - 34 PY - 2002 DA - 2002/02 SN - 15 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5438.html KW - Singularity KW - semilinear equation KW - positive solution AB - In this paper, we consider the existence and nonexistence of positive solutions to semilinear elliptic equation -Δu = K(x)(1-|x|)^{-λ_u^q} in the unit ball B with 0-Dirichlet boundary condition. Our main tools are based on the interior estimates of the Schauder type, the Schauder fixed point theorem and the pointwise estimates for Green functions.
