Coef: Ring
Expon: OrderedAbelianMonoid
UnivariatePowerSeriesCategory is the most general univariate power series category with exponents in an ordered abelian monoid. Note: this category exports a substitution function if it is possible to multiply exponents. Note: this category exports a derivative operation if it is possible to multiply coefficients by exponents.

multiplies all exponents of the power seriesf
by the positive integern
.
- one?: % -> Boolean
from MagmaWithUnit
- opposite?: (%, %) -> Boolean
from AbelianMonoid
- order: % -> Expon
order(f)
is the degree of the lowest order non-zero term inf
. This will result in an infinite loop iff
has no non-zero terms.

- terms: % -> Stream Record(k: Expon, c: Coef)
terms(f(x))
returns a stream of non-zero terms, where a a term is an exponent-coefficient pair. The terms in the stream are ordered by increasing order of exponents. Warning: If the seriesf
has only finitely many non-zero terms, then accessing the resulting stream might lead to an infinite search for the next non-zero coefficient.
- truncate: (%, Expon) -> %
truncate(f, k)
returns a (finite) power series consisting of the sum of all terms off
of degree<= k
.
- truncate: (%, Expon, Expon) -> %

returns a (finite) power series consisting of the sum of all terms off
