Query: Absence of superconductivity in the 2D Hubbard model   After receiving a number of comments and reviews from our colleagues who have
suggested that our results could be greatly improved by other methods of
extrapolation, we have decided to withdraw our paper entitled "Absence of
superconductivity in the 2D Hubbard model" until we can perform these
calculations.
