I do have a question on the isomorphism part: the map phi as defined in the paper does seem to preserve addition, but it may not preserve multiplication (I tried with n = 4 and a = b = 1+x^3, and i = 2). Maybe I'm wrong and someone wiser can advise me...hao chenhttp://www.blogger.com/profile/14472666267115070002noreply@blogger.comtag:blogger.com,1999:blog-3329110015361344577.post-9353571722554435962016-09-07T01:54:53.049+02:002016-09-07T01:54:53.049+02:00Hi there:) I was reading the paper today and I was...Hi there:) I was reading the paper today and I wasn't sure if the two rings are isomorphic in the paper as claimed. The map phi may not preserve products. (I tried it with n = 4 and p = p' = 1 + x^3 and i = 2). So it is not clear to me that the technique of Dowlin et al. is equivalent to your approach above. Maybe I am just wrong :) chipmateshttp://www.blogger.com/profile/16847766283075644215noreply@blogger.com
