Corings, their dual rings and relative (co)Hochschild cohomology
Jonathan Lindell
We show for a coring which is finitely generated projective as a left module that the Cartier cohomology is isomorphic to the relative Hochschild cohomology of the right algebra. F…

On the first relative Hochschild cohomology
Jonathan Lindell, Lleonard Rubio y Degrassi
In this paper we investigate the Lie algebra structure of the first relative Hochschild cohomology. Let be finite-dimensional basic -algebras over an algebraically closed…
