Abstract With the aid of the differential real-space method we derive exact renormalization group (RG) equations for the Gaussian model ind dimensions. The equations involved + 1 spatially dependent nearest-neighbor interactions. We locate a critical fixed point and obtain the exact thermal critical indexy T = 2. A special trajectory of the full nonlinear RG transformation is found and the free energy of the corresponding initial state calculated.
