Query: Algebra properties for Besov spaces on unimodular Lie groups   We consider the Besov space $B^{p,q}_\alpha(G)$ on a unimodular Lie group $G$
equipped with a sublaplacian $\Delta$. Using estimates of the heat kernel
associated with $\Delta$, we give several characterizations of Besov spaces,
and show an algebra property for $B^{p,q}_\alpha(G) \cap L^\infty(G)$ for
$\alpha>0$, $1\leq p\leq+\infty$ and $1\leq q\leq +\infty$. These results hold
for polynomial as well as for exponential volume growth of balls.
