In this paper, some min–max theorems for even and C1 functionalsestablished by Ghoussoub are extended to the case of functionals that are the sum of alocally Lipschitz continuous, even term and a convex, proper, lower semi-continuous,even function. A class of non-smooth functionals admitting an unbounded sequence of critical values is also pointed out.
