Commutator products in skew Laurent series division rings
Hau-Yuan Jang, Wen-Fong Ke
In 1965, Baxter established that a simple ring is either a field or that every one of its elements can be expressed as a sum of products of commutator pairs. In a recent paper, Gar…

Mikhail Chebotar, Wen-Fong Ke, Pjek-Hwee Lee +1
We prove that the ring of polynomials in several commuting indeterminates over a nil ring cannot be homomorphically mapped onto a ring with identity, i.e. it is Brown-McCoy radical…
