Note on the multiplicity of solutions for nonlinear scalar field equations with a critical inverse-square potential

Bartosz Bieganowski, Daniel Strzelecki

We are interested in the multiplicity of solutions to the following scalar field equation $$ -Δu - \frac{(N-2)^2}{4|x|^2} u = g(u), \quad \mbox{in } \mathbb{R}^N \setminus \{0\}. $…
