Abstract: | The effect of an isolated impurity on local static critical properties is examined by extrapolating exact high-temperature series. In accord with results of alternative methods no change in the critical exponents is found. The amplitudes of the singularities change in general, but a special choice of the nature of the impurity may even leave the amplitudes unchanged. This provides a convenient situation for numerical tests. |
