Abstract
The paper is concerned about the existence of solutions with prescribed -norm to the following Kirchhoff-type equation
where
or
,
. Noting that 14/3 is the mass critical exponent, a Pohozaev constraint method is adopted in two cases. In the mass mixed critical case, i.e.,
, we get a normalized solution to above equation with small enough μ by Ekeland's variational principle. In the mass supercritical case, i.e.,
, we obtain a positive ground state normalized solution, and energy comparison argument is used in the Sobolev critical case.
