Differentially trivial left Noetherian rings
We characterize left Noetherian rings which have only trivial derivations.

Divisible subgroups of Brauer groups and trace forms of central simple algebras.
Dual dimension of modules over normalizing extensions.
Let S = Σi=1n Rai be a finite normalizing extension of R and suppose that SM is a left S-module. Denote by crk(A) the dual Goldie dimension of the module A. We show that crk(RM) ≤ n · crk(SM) if either SM is artinian or the group homomorphism M → aiM given by x → aix is an isomorphism.
