witt(ZZ,PolynomialRing) -- Builds a Witt ring.

Function: witt (missing documentation)
Usage:

witt(n, R)
Inputs:
- n, an integer,
- R, a polynomial ring,
Outputs:
- an instance of the type WittPolynomialRing,

Description

Given an integer $n \geq 1$ and a polynomial ring R of positive prime characteristic, this produces the n-th witt ring $W_n(R)$ of R.

i1 : R = (ZZ/3)[x,y,z];

i2 : WR = witt(2, R)

o2 = Witt (R)
         2

o2 : WittPolynomialRing

Ways to use this method:
