Abstract
We present a solution of the infinite dimensional Hubbard model obtain ed by the numerical renormalization group method. This method gives di rectly the dynamical response in real frequency at zero temperature, a nd also gives reliable estimation of static quantities such as the ele ctronic specific heat near absolute zero. We note technical points whi ch need due care in applying this method.
