On Weak (α, δ)-Compatible Rings

For a ring endomorphism α and an α-derivation δ, we introduce the notion of weak (α, δ)-compatible rings, that is a generalization of α-rigid rings and (α, δ)-compatible rings. We first observe the basic properties of weak (α, δ)-compatible rings, and extend the class of weak (α, δ)compatible rings through various ring extensions. We next study on the relationship between the ideal quotient property of the ring R and that of the Ore extension R[x; α, δ] in case R is weak (α, δ)-compatible.
