DESCRIPTION:In joint work with Nancy Hingston\, we show that the Goresky-H
 ingston coproduct\, just like the Chas-Sullivan product\, is homotopy inva
 riant. Unlike the Chas-Sullivan product\, this coproduct is a "compactifie
 d operation"\, coming from a certain compactification of the moduli space 
 of Riemann surfaces. I&#39\;ll give an idea of the ingredients used in the
  proof.
