This package extends the Maxima function stirling0. The function stirling0 is used internally by the limit code to find asymptotic expansions for gamma, factorial, and polylogarithm expressions. The asymptotic_expansion package extends stirling0 to handle more cases. There are no user-level functions in this package.

The asymptotic_expansion package and the three associated files that are described below are not ready for general work. The three associated files are:

• simplimexpt is a new implementation of the function that computes the limit of an exponential expression.

• my-infsimp is a new implementation of the functions simpab, simpinf, and infsimp. Each of these three functions are used internally by the limit code to do extended real arithmetic. The intent is to make these functions handle more cases and to make these functions easier to extend and fix.

• continuous_p is a function that attempts to determine if an expression is continuous.
