meet -- meet operation in intersection lattice

Synopsis

• Usage:

  meet(F,G)

• Inputs:
  • F, an intersection of hyperplane(s), a flat
  • G, an intersection of hyperplane(s), another flat from the same arrangement
• Outputs:
  • H, an intersection of hyperplane(s), the flat of greatest codimension that is contained in both F and G. If one identifies flats with subspaces, this is the Minkowski sum of subspaces F and G.

Description

The operator Flat ^ Flat can be used as a synonym.
