Query: On the Lipschitz character of orthotropic $p-$harmonic functions   We prove that local weak solutions of the orthotropic $p-$harmonic equation
are locally Lipschitz, for every $p\ge 2$ and in every dimension. More
generally, the result holds true for more degenerate equations with orthotropic
structure, with right-hand sides in suitable Sobolev spaces.
