Bifurcation of non-radial solutions from radial solutions of a semilinear elliptic equation with negative exponent in expanding annuli of ℝ2 is studied. To obtain the main results, we use a blow-up argument via the Morse index of the regular entire solutions of the equation
The main results of this paper can be seen as applications of the results obtained recently for finite Morse index solutions of the equation
with N ⩾ 2 and p > 0.
