semigroupFromMu -- Inverse of the function mu

Usage:

L = semigroupFromMu mm
Inputs:
- mm, a list, of m-1 positive integers
Outputs:
- L, a list, minimal generators of a semigroup

Description

if A = {a_1..a_(m-1)} is the Apery set of a semigroup L, then mu L is the sequence of numbers (a_i -i)/m. semigroupFromMu is the inverse operation.

i1 : L = {6,9,13,16}

o1 = {6, 9, 13, 16}

o1 : List

i2 : mm = mu L

o2 = {2, 4, 1, 2, 4}

o2 : List

i3 : semigroupFromMu mm

o3 = {6, 9, 13, 16}

o3 : List
