Asymptotics and special functions 1st edition frank olver routl. In mathematics, an asymptotic expansion, asymptotic series or poincare expansion after henri poincare is a formal series of functions which has the property that truncating the series after a finite number of terms provides an approximation to a given function as the argument of the function tends towards a particular, often infinite, point.
