> | ### D.15.22 stanleyreisner_lib Library: stanleyreisner.lib Purpose: Deformations of Stanley-Reiser ideals Authors: Overview: Firstly, we implement the graded pieces has certain degree of cotangent modules T1 and T2 for a general Stanley-Reiser ring. And the graded pieces of homomorphisms are represented by lists of integers. Types: Homomorphism class of homomorphisms Procedures:
> D.15.22.1 T1 |  | compute first order deformations
> D.15.22.2 T2 |  | compute second order deformations
> D.15.22.3 makeQPoly |  | create a QPoly
> D.15.22.4 fPiece |  | create a FirstOrderDeformation
> D.15.22.5 sPiece |  | create a SecondOrderDeformation
> D.15.22.6 makeLinks |  | create a FirstOrderDeformation of the links
