gfanFanProduct -- computes the product of polyhedral fans

Synopsis

• Usage:

  P = gfanFanProduct(F,G)

• Inputs:
  • F, an instance of the type Fan, a polyhedral fan
  • G, an instance of the type Fan, a polyhedral fan
• Optional inputs:
  • i1
  • i2
• Outputs:
  • P, an instance of the type Fan, the product of F and G

Description

i1 : QQ[x,y];

i2 : F = gfanToPolyhedralFan {markedPolynomialList{{x}, {x+y}}}

o2 = F

o2 : Fan

i3 : G = gfanToPolyhedralFan {markedPolynomialList{{y^2}, {x+y^2}}}

o3 = G

o3 : Fan

i4 : gfanFanProduct(F,G)

o4 = (Fan{...1...}, {1})

o4 : Sequence

This program takes two polyhedral fans and computes their product.
Options:
