• C: CommutativeRing

QEtaGradedAlgebra(C) lists the minimal signatures for running the functions in the QEtaPackage. Mathematically seen is it a C-algebra that is ZZ-graded. Simplest example is a univariate polynomial ring over C, but since it is expected that respective domains will be created on the fly, we list here only the functions that are actually used in QEtaSambaPackage.

qetaCoefficient: (%, Integer) -> C

qetaCoefficient(x, n) returns the coefficient corresponding to grade n.

qetaGrade: % -> Integer

qetaGrade(x) returns the grade of an element. The qetaGrade of 0 is undefined. Any element x with qetaGrade(x)<0 will be considered to be zero.

qetaLeadingCoefficient: % -> C

qetaLeadingCoefficient(x) returns qetaCoefficient(x, qetaGrade x). The qetaLeadingCoefficient of 0 is undefined.
