org.uacalc.alg.AlgebraFromMinimalSets

All Implemented Interfaces:

Algebra, SmallAlgebra

public class AlgebraFromMinimalSets
extends BasicAlgebra
implements SmallAlgebra

Starting with an algebra B which is permutational (nonconstant unary polynomials are permutations) and a geometry for the minimal sets, this constructs an algebra A with tame minimal sets, having B as a minimal set. Initially we will assume the geometry has 3 minimal sets, B, C, D, with C And D disjoint and the intersection of B and C just 0 and B and D the last element of B.

If n is the size of A and k is the size of each minimal set, we can specify the geometry of a list of maps 0 to k-1 into A.

                              java.util.List<java.lang.Integer> connectPts)

If k is the cardinality of minAlg, each map maps k = {0,..., k-1} one-to-one into n = {0,...,n-1}. The first map must be the identity. Each element of n must be in the range of at least one map. Given any two elements of n, there are overlapping ranges of the maps going from on to the other.

Parameters:

name -

minAlg - a permutational algebra

maps -
