Abstract
We explore the properties of the non-commutative Grassmann algebra to study the unidimensional Generalized Hubbard model, obtaining the analytical exp ressions for the first three terms in the high temperature expansion of its grand canonical partition function, with no restrictions to the constant p arameters of the model. We obtain corrections to known results, in the case of half-filled band with hopping constants t = 0 and X = 0. (C) 1999 Elsev ier Science B.V. All rights reserved.
