Of these nine candidates, please indicate the paper or papers which you think will contibute most significantly to future research in 4D quantum gravity. Multiple choice is possible in the poll, so pick several if you wish. http://arxiv.org/abs/0909.4221 Ashtekar, Campiglia, Henderson http://arxiv.org/cits/0909.4221 Loop Quantum Cosmology and Spin Foams http://arxiv.org/abs/0909.3426 't Hooft http://arxiv.org/cits/0909.3426 Quantum Gravity without Space-time Singularities or Horizons http://arxiv.org/abs/0909.3265 Benedetti, Machado, Saueressig http://arxiv.org/cits/0909.3265 Four-Derivative Interactions in Asymptotically Safe Gravity http://arxiv.org/abs/0909.0939 Lewandowski, Kamiński, Kisielowski http://arxiv.org/cits/0909.0939 Spin-Foams for All Loop Quantum Gravity http://arxiv.org/abs/0908.4476 Christensen, Khavkine, Livine, Speziale http://arxiv.org/cits/0908.4476 Sub-leading Asymptotic Behaviour of Area Correlations in the Barrett-Crane Model http://arxiv.org/abs/0907.4323 Dittrich, Bahr http://arxiv.org/cits/0907.4323 Improved and Perfect Actions in Discrete Gravity http://arxiv.org/abs/0907.4238 Woodard http://arxiv.org/cits/0907.4238 How Far Are We from the Quantum Theory of Gravity? http://arxiv.org/abs/0907.4064 Krasnov http://arxiv.org/cits/0907.4064 Gravity as BF Theory Plus Potential http://arxiv.org/abs/0907.2440 Barrett, Dowdall, Fairbairn, Hellmann, Pereira http://arxiv.org/cits/0907.2440 Lorentzian Spin Foam Amplitudes: Graphical Calculus and Asymptotics I'll try to give a thumbnail for each one, and say why it might prove important. The list is most recent first so I'll review them in that order.
