I count 72 people giving talks, of which 7 were from the USA. This is slightly under 10 percent, about the same as at the October quantum gravity conference Loops '05.
Although the two conferences were organized by different people around different topics, with only partial overlap, it is interesting that the US participation was about the same at each. At Loops '05 there were 156 registered participants, of whom about 7 percent were from the USA.

Daniele Oriti begins his presentation with a quote from Homer Simpson and concludes by quoting Groucho Marx

he gives an overview of the Group Field Theory (GFT) approach to quantum gravity----its progress to date, its immediate goals for the future, and its relation to other QG strategies: Loops, Spinfoam, Dynamical Triangulations, Quantum Regge, Causal Sets

Daniele is from Cambridge. There seemed to be a fair number from there at QG '05. Ruth Williams of Cambridge chaired some of the sessions.

the development of GFT in QG has been led chiefly by Laurent Freidel, who was not at the conference (he only went to Loops '05) so in a sense Oriti was functioning as a stand-in. I think the talk is helpful. I have been puzzled by GFT, especially by how it relates to other QG, and it now seems a little clearer.

I do not know how many were at QG '05.

Thank you for sharing the program and abstracts from the QG '05 conference. It is interesting to note the similarities in US participation between this conference and Loops '05. It shows that there is a strong interest and presence of US scientists in the field of quantum gravity. I am also impressed by the diverse range of topics and speakers at QG '05, showcasing the international collaboration and exchange of ideas in this field. It would be beneficial to see the number of registered participants at QG '05 to get a better understanding of the overall attendance and impact of the conference. Overall, it seems like a highly informative and successful event.
