In this paper, we study the critical
‐Laplacian equation of Kirchhoff type
where
is the Kirchhoff function,
with
and
is a parameter,
, and the potentials
and
vanish at infinity. Under some suitable assumptions on
, by using the constraint minimization approach, we obtain a least energy sign‐changing solution
to this problem if
is large enough and show the energy of
is strictly larger than twice that of the ground state solutions. Moreover, by considering a wider class of
and
, we exploit the truncation argument to find a nontrivial solution if
is sufficiently large via some analytic skills.
