In this article, we consider a K − algebra R with a partial action α of a finite group G on it. If each g Dg is generated by a central idempotent of R, we answer the question: If P1 ⊂ P2 are primes in R and P2 minimal over P2∩ Rα, does some prime P1 exist in Rα such that P1 is minimal over P2∩ Rα, and P1⊂p2? Similar results are proved by interchanging R and Rα.

Abstract


In this article, we consider a K − algebra R with a partial action α of a finite group G on it. If each g Dg is generated by a central idempotent of R, we answer the question: If P1 ⊂ P2 are primes in R and P2 minimal over P2∩ Rα, does some prime P1 exist in Rα such that P1 is minimal over P2∩ Rα, and P1⊂p2? Similar results are proved by interchanging R and Rα.
