Abstract
This paper is concerned with the existence of positive solutions to Schrödinger-Kirchhoff-type equations
where a and b are two positive constants,
and
is a potential function. Under certain assumptions on V, we prove that
has no ground state solution. However, we can show
has a positive bound state solution by applying a new version of the global compactness lemma and the linking theorem.
