Abstract
By means of a cumulant expansion method, we investigate the incommensurate phase in the low doping region of the two dimensional single-band Hubbard m odel. We calculate the spin magnetic susceptibility as a function of doping and analyze the effect of a Van Hove singularity on a commensurate-incomme nsurate transition. A comparison with the experimental results of LSCO is d iscussed.
