| contents | 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 of M-P type. We merely address the Sobolev critical cases since the Sobolev subcritical ones can be addressed by following similar arguments and are easier. Our framework is based on some important observations, that, to the best of our knowledge, have not appeared in previous literatures. Using these observations, we firstly establish the existence of a normalized ground state solution, whose existence is unknown so for. Then we use some novel ideas to obtain the second positive normalized solution, which is of M-P type. It seems to be the first time in the literatures to get two positive solutions under our settings, even in the Sobolev subcritical cases. We further remark that our framework is applicable to many other equations. |
