Large solutions to elliptic equations involving fractional Laplacian
Annales de l'I.H.P. Analyse non linéaire, Tome 32 (2015) no. 6, pp. 1199-1228.

The purpose of this paper is to study boundary blow up solutions for semi-linear fractional elliptic equations of the form

{(-Δ) α u(x)+|u| p-1 u(x)=f(x),xΩ,u(x)=0,xΩ ¯ c , lim xΩ,xΩu(x)=+,(0.1)
where p>1, Ω is an open bounded C 2 domain of N , N2, the operator (-Δ) α with α(0,1) is the fractional Laplacian and f:Ω is a continuous function which satisfies some appropriate conditions. We obtain that problem (0.1) admits a solution with boundary behavior like d(x) -2α p-1 , when 1+2α<p<1-2α τ 0 (α), for some τ 0 (α)(-1,0), and has infinitely many solutions with boundary behavior like d(x) τ 0 (α) , when max {1-2α τ 0 +τ 0 (α)+1 τ 0 ,1}<p<1-2α τ 0 . Moreover, we also obtained some uniqueness and non-existence results for problem (0.1).
