Abstract:
In this article we study the Schrodinger equation
where
is a bounded domain in
and f(x,u) is
asymptotically linear at infinity with respect to u.
Inspired by the works of Salvatore [14] on sign-changing solutions,
in which
is asymptotically linear at zero with respect to u,
we prove, via the constraint variational method and the quantitative
deformation lemma, that the equation possesses one sign-changing solution
with exactly two nodal domains.
