coupleRing -- builds a couple ring

Synopsis

Usage:

coupleRing(R,r,e,f)
Inputs:
- R, a ring, the coefficients
- r, an integer, the page number
- e, a symbol
- f, a symbol
Optional inputs:
- Degrees (missing documentation) => ..., default value {{1, 0}, {-2, 2}}
Outputs:
- a ring, R[e_r,f_r,Degrees=>{{1,0},{-2,2}}]

Description

These default degrees are chosen to meet the conditions of expectCoupleRing. Other degrees are possible using the optional argument Degrees or by building the couple ring by hand directly.

i1 : Q = coupleRing(QQ,7,e,f)

o1 = Q

o1 : PolynomialRing

i2 : describe Q

o2 = QQ[e , f , Degrees => {{1}, {-2}}, Heft => {1..2}, MonomialOrder => {MonomialSize => 32}, DegreeRank => 2]
