We solve analytically the scaling equations in the half-filled Httbbard model on the two-dinaensional square lattice. The eqtrations are cotrpled differential equations for the vertexfunctions, which were derived independently by Schtrlz and Dzyaloshinskii to take the electron-correlation efl'ects into accotrnt beyond the randoraa ph?xse approximation. Our analytical soJtutionconfirms the results so far obtained on the scaling equations.
