Exact number of positive solutions and existence of sign-changing solutions with prescribed mass for NLS on bounded domains
Linjie Song, Wenming Zou
Given , we study the elliptic problem: \begin{align*} \text{ find } (u,λ) \in H_0^1(Ω) \times \mathbb{R} \text{ such that } -Îu + λu = |u|^{p-2}u \text{ in } Ω\text{ an…

Two Positive Normalized Solutions on Star-shaped Bounded Domains to the Brézis-Nirenberg Problem, I: Existence
Linjie Song, Wenming Zou
We develop a new framework to prove the existence of two positive solutions with prescribed mass on star-shaped bounded domains: one is the normalized ground state and another is o…
