## An Alternative Approach of Evaluating the Validity of Perturbative Calculations with Respect to Convergence of Power Series Based on Polynomials for the Inverse Function

**Authors:** Andrej Liptaj

Results of perturbative calculations in quantum physics have the form of truncated power series in a coupling constant. In order to evaluate the uncertainty of such results, the power series of the inverse function are constructed. These are inverted and the difference between the outcome of this procedure and the initial power series is taken as uncertainty.
