We calculate the Hall constant RH(e~, T) for the high T~ materials Laz\_xSrxCuO 4 and YBa2Cu3Ov-x using the 2D Hubbard model, on a cluster of dimension (2 × 3). Close to half filling, at low temperatures and high frequency, we find that Rn(~/3) is electronlike in the weak correlation regime and in t
