Differential smoothness of skew polynomial rings
Tomasz Brzeziński, Christian Lomp
It is shown that, under some natural assumptions, the tensor product of differentially smooth algebras and the skew-polynomial rings over differentially smooth algebras are differe…
Ring theoretical properties of affine cellular algebras
Paula A. A. B. Carvalho, Steffen Koenig, Christian Lomp +1
As a generalisation of Graham and Lehrer's cellular algebras, affine cellular algebras have been introduced in [12] in order to treat affine versions of diagram algebras like affin…
A note on semicentral Idempotents
Christian Lomp, Jerzy Matczuk
In this note we answer the question raised by Han et al. in J. Korean Math. Soc (2014) whether an idempotent isomorphic to a semicentral idempotent is itself semicentral. We show t…
A counterexample for a problem on quasi Baer modules
Christian Lomp
In this note we answer two questions on quasi-Baer modules raised by Lee and Rizvi in J.Algebra (2016).
