Query: The best m-term approximation with respect to polynomials with constant
  coefficients   In this paper we show that that greedy bases can be defined as those where
the error term using $m$-greedy approximant is uniformly bounded by the best
$m$-term approximation with respect to polynomials with constant coefficients
in the context of the weak greedy algorithm and weights.
