numericalAffineSpace -- affine space as a numerical variety

Description

Constructs a numerical variety representing the complex affine space corresponding to the given coordinate ring.

i1 : R = CC[x,y]	

o1 = R

o1 : PolynomialRing
 
i2 : V := numericalAffineSpace R

o2 = a "numerical variety" with components in
     dim 2:  (dim=2,deg=1)

o2 : NumericalVariety
 
i3 : C := first components V

o3 = (dim=2,deg=1)

o3 : WitnessSet
 
i4 : equations C

o4 = {}

o4 : List
 
i5 : slice C

o5 = {(.892712 + .673395*ii)x + (.0258884 + .714827*ii)y - .461944 -
     ------------------------------------------------------------------------
     .775187*ii, (.29398 + .632944*ii)x + (.89189 + .231053*ii)y - .909047 -
     ------------------------------------------------------------------------
     .314897*ii}

o5 : List
 
i6 : points C

o6 = {{.364967-.0660072*ii, .826623-.098325*ii}}

o6 : VerticalList
