QuadricSurface -- type of HashTable

Description

QuadricSurface is a type of HashTable storing information about a smooth quadric surface in P^3. The keys of a QuadricSurface are: IntersectionPairing, HyperplaneClass, CanonicalClass, Ideal.

Methods that use an object of class QuadricSurface:

  • divisor(List,QuadricSurface) -- see divisor -- creates a Divisor
  • ideal(QuadricSurface) -- extracts the ideal of a surface
  • net(QuadricSurface) -- displays the ideal of the QuadricSurface
  • smoothDivisors(ZZ,QuadricSurface) -- see smoothDivisors -- produces a list of smooth divisors of a given degree on a surface

For the programmer

The object QuadricSurface is a type, with ancestor classes HashTable < Thing.
