Chen's biharmonic conjecture is well-known and stays open: The only
biharmonic submanifolds of Euclidean spaces are the minimal ones. In
this paper, we consider an advanced version of the conjecture,
replacing $Delta$ by its extension, $L_1$-operator
($L_1$-conjecture). The $L_1$-conjecture states that any
$L_1$-biharmonic Euclidean hypersurface is 1-minimal. We prove that
the $L_1$-conjecture is true for $L_1$-biharmonic hypersurfaces with
three distinct principal curvatures and constant mean curvature of a
Euclidean space of arbitrary dimension.
