COMPLETELY PRIME ONE-SIDED IDEALS IN SKEW POLYNOMIAL RINGS

Abstract

AbstractLet R = K[x, σ] be the skew polynomial ring over a field K, where σ is an automorphism of K of finite order. We show that prime elements in R correspond to completely prime one-sided ideals – a notion introduced by Reyes in 2010. This extends the natural correspondence between prime elements and prime ideals in commutative polynomial rings.
