centralElements -- Finds central elements in a given degree

Synopsis

Description

If the given noncommutative ring has central elements of the specified degree, this method returns a basis for the space of central elements in that degree.

i1 : B = threeDimSklyanin(QQ,{1,1,-1},{x,y,z})
Using numthreads = 0

o1 = B

o1 : FreeAlgebraQuotient
i2 : centralElements(B,2)

o2 = | yx y2 yz zx zy z2 |

             1       6
o2 : Matrix B  <--- B
i3 : centralElements(B,3)

o3 = | y2x y3 yzx yzy zyx zy2 zyz z2x z2y z3 |

             1       10
o3 : Matrix B  <--- B
