We consider the following singular semilinear problem

$\left\{ \begin{array}{l} - \Delta u(x) = a(x){u^\sigma }(x),{\rm{ }}x \in \Omega \backslash \{ 0\} ({\rm{in\;the\;distributional\;sense}}),\\\;u > 0,{\rm{ on}}\;\Omega \backslash \{ 0\} ,\\\mathop {\lim }\limits_{\left| x \right| \to 0} \frac{{u(x)}}{{\ln \left| x \right|}} = 0,\\u(x) = 0,\;x \in \partial \Omega ,\end{array} \right.$

where

$σ <1,$

$Ω $

is a bounded regular domain in

$\mathbb{R}^{2}$

with

$0∈ Ω .$

The weight function

$a(x)$

is requiredto be positive and continuous in

$Ω \backslash \{0\}$

with thepossibility to be singular at

$x = 0$

and/or at the boundary

$\partial Ω. $

When the function

$a$

satisfies sharp estimates related to Karamataclass, we prove the existence and global asymptotic behavior of a positivecontinuous solution on

$\overline{Ω }\backslash \{0\}$

which couldblow-up at

$0$

.

Keywords: Singular positive solution, Green's function, Karamata class, Kato class, blow-up.
