    Comment from the referee (August, 2007): "We highly recommend the publication of this manuscript."
  3. Zhi-Wei Sun, How to unify covering systems, restricted sumsets and zero-sum problems,
    a talk given at EACAC2 (Fukuoka, Nov. 21, 2003) with some historic remarks.
  4. Comment from I. Ruzsa (May 1, 2003): "Certainly these are very interesting questions."
  5. Comment from D. Zeilberger (May 1, 2003): "Sounds interesting! Good luck with developing your new theory."
  6. Comment from Y. N. Yeh (Jan. 1, 2004): "I have read your wonderful paper. You tell people the secret to connect three important topics in combinatorial number theory. You are a very excellent mathematician!"
  7. Comment from a paper of V. Dimitrov: "We note that a deep unification of zero-sum problems, subset sums and covers of Z (the three main areas of additive number theory, each initiated by P. Erdos) was very recently established in [Zhi-Wei Sun, Electron. Res. Announc. Amer. Math. Soc. 9(2003), 51-60]."
  8. Comment from a letter of P. Mills (July 22, 2004): "Very deep work!"
  9. Comment from Noga Alon (Nov. 5, 2008): "In his paper on zero-sum problems, subset sums and covers of the integers, Sun found beautiful, unexpected relations between three well studied topics."
