Finding critical points whose polarization is also a critical point

Marco Squassina, Jean Van Schaftingen


We show that near any given minimizing sequence of paths for the mountain pass lemma,
there exists a critical point whose polarization is also
a critical point. This is
motivated by the fact that if any polarization of a critical point is also a critical point and the Euler-Lagrange equation is a second-order semi-linear
elliptic problem, T. Bartsch, T. Weth and M. Willem
(J. Anal. Math., 2005) have proved that the critical point is axially symmetric.
