Divisor :: divisor(..., AmbRing => ...)

divisor(..., AmbRing => ...) -- optional arguments to specify the ambient ring in the divisor constructor

Synopsis

Usage:
D = divisor( ..., AmbRing=>R)
Inputs:
- R, a ring, an option to specify a particular ambient ring
Outputs:
- D, an object of class BasicDivisor

Description

Construct a divisor as a formal sum of height one prime ideals whose coefficients are real numbers

i1 : R = QQ[x,y,z];

i2 : D = divisor({},{}, AmbRing=>R)

o2 = 0, the zero divisor

o2 : WeilDivisor on R

i3 : D = divisor({}, {})

o3 = 0, the zero divisor

o3 : WeilDivisor on ZZ

Further information

Default value: null
Function: divisor -- constructor for (Weil/Q/R)-divisors
Option name: AmbRing -- an option used to tell divisor construction that a particular ambient ring is expected.
