Given and , in this note, we are interested in construction of non-radial solutions for the following equation
in the whole space . The construction is basically due to Louis Dupaigne and mainly depends on the unique radial solution of the equation.
To start our construction, let us recall that there is a unique radial solution, denoted by , of the equation such that and . Moreover, is globally defined and blows up at infinity at a fixed rate
where and , see a paper by Yang and Guo published in J. Partial Diff. Eqns. in 2005.
Notice that
Hence, integrating both sides of the equation for gives
