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
