Название: Fast algorithms for composition and reversion of multivariate power series
Авторы: Brent R.P., Kung H.T.
In our earlier paper, we gave fast algorithms for manipulating univariate pcjwsc series. In this paper, fast algorithms for composition and reversion of multivariate power series are presented. The new algorithms requires substantially less operations than the best previously known counterparts. The amount of reduction in the number of required operations increases rapidly as the number o£ variables in multivariate power series increases.
