UnivariatePowerSeriesCategory(Coef, Expon)ΒΆ

pscat.spad line 51 [edit on github]

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.

elt: (%, %) -> % if Expon has SemiGroup

from Eltable(%, %)

elt: (%, Expon) -> Coef

elt(f(x), r) returns the coefficient of the term of degree r in f(x). This is the same as the function coefficient.

eval: (%, Coef) -> Stream Coef if Coef has ^: (Coef, Expon) -> Coef

eval(f, a) evaluates a power series at a value in the ground ring by returning a stream of partial sums.

extend: (%, Expon) -> %

extend(f, n) causes all terms of f of degree <= n to be computed.

multiplyExponents: (%, PositiveInteger) -> %

multiplyExponents(f, n) multiplies all exponents of the power series f by the positive integer n.

from MagmaWithUnit

opposite?: (%, %) -> Boolean

from AbelianMonoid

order: % -> Expon

order(f) is the degree of the lowest order non-zero term in f. This will result in an infinite loop if f has no non-zero terms.

order: (%, Expon) -> Expon

order(f, n) = min(m, n), where m is the degree of the lowest order non-zero term in f.

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 series f 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 of f of degree <= k.

truncate: (%, Expon, Expon) -> %

truncate(f, k1, k2) returns a (finite) power series consisting of the sum of all terms of f of degree d with k1 <= d <= k2.
