Obstructions to Deformations of DG Modules

Trina Armstrong, Ron Umble

Let k be a field and n > 0. There exists a DG k-module (V,d) and various approximations d + t d_1 + t^2 d_2 + ... + t^n d_n to a differential on V[[t]], one of which is a non-trivi…

The Deformation Complex For DG Hopf Algebras

Ronald Umble

Let H be a differential graded Hopf algebra over a field k. This paper gives an explicit construction of a triple cochain complex that defines the Hochschild-Cartier cohomology of…
