triangleRing -- builds a triangle ring

Synopsis

Usage:

triangleRing(R,d,e,f)
Inputs:
- R, a ring, the coefficients
- d, a symbol
- e, a symbol
- f, a symbol
Optional inputs:
- Degrees (missing documentation) => ..., default value {{0, 2}, {1, 0}, {-2, 2}}
Outputs:
- a ring, R[d,e,f,Degrees=>{{0,2},{1,0},{-2,2}}]/(d^2,e^3)

Description

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

i1 : Q = triangleRing(QQ,d,e,f)

o1 = Q

o1 : QuotientRing

i2 : describe Q

     QQ[d, e, f]
o2 = -----------
         2   3
       (d , e )

i3 : expectTriangleRing Q
