Adjust -- adjust the multi-degree

Adjust -- an option used when creating a polynomial ring to specify a linear function for transforming multi-degrees of monomials into multi-degrees whose first component is positive, for internal use.

This facility is used in particular by (Ext,Module,Module).

i1 : R = ZZ[x,y, Degrees => {-1,-2}, 

          Repair => d -> -d,

          Adjust => d -> -d];

i2 : degree \ gens R



o2 = {{-1}, {-2}}



o2 : List

i3 : transpose vars R



o3 = {1} | x |

     {2} | y |



             2       1

o3 : Matrix R  <--- R
