Mass concentration of minimizers for $L^2$-subcritical Kirchhoff energy functional in bounded domains

Chen Yang, Shubin Yu, Chun-Lei Tang

We are concerned with $L^2$-constraint minimizers for the Kirchhoff functional $$ E_b(u)=\int_Ω|\nabla u|^2\mathrm{d}x+\frac{b}{2}\left(\int_Ω|\nabla u|^2\mathrm{d}x\right)^2+\int_…
