by Loredana Lanzani

Vol. 8 No. 3 (2013) P.389~P.398

ABSTRACT

We give new examples of linear differential operators of order $k=2m+1$ (any given odd integer) that are invariant under the isometries of $\mathbb R^n$ and satisfy so-called $L^1$-duality estimates and div/curl inequalities.

KEYWORDS
