Nature of problem:
The program provides a tool for computations which are likely to occur in all branches of physics and elsewhere. Based on methods discussed by Zyczkowski some time ago, the paper presents procedures, written in REDUCE, for manipulating generalized power series. These series include ordinary power series as special cases. The procedures handle the multiplication and division of two series, the raising to a power of a series, the substitution of one series into another, the reversion of a series, and the elimination of a common parameter from two series. A procedure is also given for the algorithm proposed by Thacher for a more general inversion problem for ordinary power series.
Mathematical formulae mainly developed by Zyczkowski are converted to procedures in symbolic algebra.
The running time depends on the number of series terms which are carried in the computation.
