This paper is devoted to deformation theory of graded Lie algebras over Z or Zl with finite dimensional graded pieces. Such deformation problems naturally appear in number theory. In the first part of the paper, we use Schlessinger criteria for functors on Artinian local rings in order to obtain universal deformation rings for deformations of graded Lie algebras and their graded representations...

The intention is for the article to be engaging and accessible to students with 1 or 2 courses in formal semantics, so I’ve tried to keep it as non-technical and empiricallyoriented as possible.
