Normalized solutions to the NLS equation in the ball for any prescribed mass

Given $ρ>0$, we consider the problem \[ \text{find $(λ,u) \in \mathbb{R} \times H_0^1(B)$ such that } \begin{cases} -Δu+λu = |u|^{p-1}u & \text{in } B \\ \int_B u^2\,dx = ρ, \end{cases} \] where $B$ is a ball in $\mathbb{R}^N$, $N \ge 1$, and $1<p<2^*-1$. Without any further restriction on $N$, $ρ$
